The following sections list the new hardware and software features supported by the Cisco series routers for Release The following sections describe the new hardware features supported by the Cisco series routers for Release The interface cards provide basic telephone service connectivity for remote router management; asynchronous Dial-on-Demand Routing DDR and dial backup; dial- and fax-out modem access; and low-density remote access server RAS services.
Note Prior to Release For example, the first 12kb to 64kb channels of a T1 circuit could form a channel group for signals sent to a frame relay network. In addition to the functionality described above, the DI VWICs enable specified DS0 channels from one port to be directly cross-connected to another port. For example, the first three DS0s of one port can be directly cross-connected to the first three DS0s of a second port. The remaining DS0s can support signals to or from other interfaces on the router.
The G. Note The G. The following sections describe the new software features supported by the Cisco series routers for Release Note A previous software version, Release Cisco IOS Telephony Service also helps download phone software images and configures and manages the Cisco IP phones in a LAN, to accommodate the telephony system of a small office with a small number of extensions. Note You need to purchase a feature license to turn this new feature on. You also need an account on Cisco.
CAS is a form of signaling used on a T1 line. With CAS, a signaling element is dedicated to each channel in the T1 frame. This type of signaling is sometimes called Robbed Bit signaling RBS because a bit is taken out or robbed from the user data stream to provide signaling information to and from the switch.
The R2 signaling is an international signaling standard that is common to channelized E1 networks. There is no single standard for R2 signaling. Cisco and Cisco routers use E1 R2 signaling to communicate with central office trunks that also use E1 R2 signaling. When packets are encapsulated by tunnel or encryption headers, Quality of Service QoS features are unable to examine the original packet headers and correctly classify the packets.
Packets traveling across the same tunnel have the same tunnel headers, so the packets are treated identically if the physical interface is congested. With the growing popularity of Virtual Private Networks VPNs , the need to classify traffic within a traffic tunnel is gaining importance. QoS features have historically been unable to classify traffic within a tunnel. The process of classifying features before tunneling and encryption is called preclassification. When the new feature is enabled, the QoS features on the output interface classify packets before encryption, allowing traffic flows to be adjusted in congested environments.
The end result is more effective packet tunneling. Cisco IOS software can classify packets and apply the appropriate QoS service before the data is encrypted and tunneled. In addition, when packets are marked using the IP Type of Service byte or differentiated services code point DSCP values, the markings are copied to the new, encrypted packet.
This allows the service provider to treat mission critical or multi-service traffic with higher priority across their network. These URLs are subject to change without notice. If it changes, point your web browser to CCO, and click the following path:. The following restrictions in Release Also, see the "Caveats" section. You can change this configuration if needed. Cisco and V router fans are always on and Cisco routers do not contain a fan.
However, the fans in Cisco , , , and routers stay off until thermally activated. When using a multipartition flash card, the various flash partitions are referred to as "flash", "flash", etc. If you specify only "flash" in a multipartition flash, the parser assumes "flash To see information for all flash partitions, enter show flash? This will list all of the valid partitions.
Then enter show flash:xx: all on each valid partition. Other rates are treated as the next lower value of a multiple of For example, an entered PCR value of is considered Booting a Cisco series router with the commands boot flash or boot system flash results in unpredictable behavior.
To work around this problem, be sure to enter a colon : following both commands for example, boot flash: or boot system flash:. Booting a Cisco series router using the command boot system tftp might not work due to insufficient memory. To work around this problem, use the command tftpdnld from the ROM monitor. This error is caveat number CSCdv Caveats describe unexpected behavior or defects in Cisco IOS software releases.
Severity 1 caveats are the most serious caveats, severity 2 caveats are less serious, and severity 3 caveats are the least serious of these three severity levels. Caveats in Release Note If you have an account with Cisco. To reach the Bug Toolkit, log in toCisco. This section describes unexpected behavior that is fixed in Release An error can occur with management protocol processing.
Please use the following URL for further information:. If the voice port is not shut, issuing the command no mgcp causes MGCP processes to shut down incorrectly. This has been observed when RQNT with embedded notifications is issued by the call agent. A failure occurs if you attempt to make fax calls T. Although some fax calls might be sent through the speed-up mechanism successfully, subsequent fax calls might fail.
A workaround is to use G. To work around this problem, clear the counters. The default IVR applies to the configured translation rule multiple times. The caveats document is updated for every maintenance release and is on Cisco. This section describes the system requirements for Release Cisco IOS Release For detailed descriptions of the new hardware features, see the documents listed in the "Platform-Specific Documents" section.
Cisco Security Access Router is an integrated VPN, Firewall, and security router providing customers with data privacy and protection while accessing information across the public IP networks. Table 2 lists the key features of the Cisco Security Access router. Operates in full- or half-duplex mode and set by default to half-duplex mode. Needs manual configuration for full-duplex support. Supports router configuration and management with a directly connected terminal or PC.
Supports up to Supports modem connection to the router, which can be configured and managed from a remote location. Configuration files can be easily downloaded to the router over a WAN connection. Router can be secured to a desktop or other surface using Kensington lockdown equipment.
The router provides Internet and intranet access and includes the following:. The Cisco router supports any combination of one or two of the following WAN interface cards:. The voice-and-data capable Cisco router provides global Internet and company intranet access and includes the following:. The Cisco router supports any combination of one or two of the following WICs, which are shared with the Cisco , , , and routers:.
The Cisco router supports any combination of one or two of the following voice interface cards, which are shared with the Cisco and routers:. The voice-and-data capable Cisco and V routers provide global Internet and company intranet access and includes the following:. The Cisco and V routers support any combination of one or two of the following WICs, which are shared with the Cisco , , , , and routers:. The Cisco and V routers support any combination of one, two or three of the following VICs, which are shared with the Cisco and routers:.
The Cisco IOS software is packaged in feature sets consisting of software images—depending on the platform. Each feature set contains a specific set of Cisco IOS features. Release The tables use the following conventions:. Note These tables might not be cumulative or list all the features in each image. These electronic documents may contain updates and modifications made after the hardcopy documents were printed.
The following sections list the new hardware and software features supported by the Cisco routers for Release The Hoot and Holler network is a multi-point four-wire audio conference network that is always up so that communication is enabled with the push of a button when needed.
Hoot and Holler networks are typically used throughout the brokerage industry to communicate morning reports and to advise traders within a firm on market movements and trading activities. In addition, this type of network is used in industries that require collaboration on a regular basis. Hoot and Holler networks are usually spread over four to eight sites but some businesses such as retail may have as many as interconnected sites.
Within a site, bridging is done locally with a standard audio or digital bridge circuit that may be part of a trading turret system. Bridging between the sites are often provided by the carrier, who provides dedicated either analog or digital four-wire connections into a central N1 bridge. The following sections contain important notes that can apply to the Cisco series routers. When using a multipartition Flash card, the various Flash partitions are referred to as flash, flash, etc.
If you specify only flash in a multipartition Flash, the parser assumes flash For example, if you enter show flash all , the parser defaults to show flash all, and only the Flash information for the first partition appears. To see information for all Flash partitions, enter show flash? This lists all of the valid partitions. Then enter show flash:xx: all on each valid partition. Other rates are treated as the next lower value of a multiple of For example, an entered PCR value of is considered Booting a Cisco series router with the commands boot flash or boot system flash results in unpredictable behavior.
To work around this problem, be sure to enter a colon : following both commands for example, boot flash: or boot system flash:. Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most serious caveats, severity 2 caveats are less serious, and severity 3 caveats are the least serious of these three levels.
Note If you have an account with Cisco. To reach the Bug Toolkit, log in toCisco. This section describes unexpected behavior that is fixed in Release An error can occur with management protocol processing. Please use the following URL for further information:. This section describes possibly unexpected behavior that are resolved in Release If a host PC uses the default MTU of bytes, the router between the server and the host would drop those packets.
Even though an ICMP message is sent to the website notifying it of the problem, some websites are programmed to ignore ICMP messages and would continue to send byte packets that will get dropped. Starting with Release Use the following IOS command:. The following sections describe the documentation available for the Cisco series routers. Typically, these documents consist of hardware and software installation guides, Cisco IOS configuration and command references, system error messages, feature modules, and other documents.
Documentation is available as printed manuals or electronic documents, except for feature modules, which are available online on Cisco.
