Cisco 2500 Series

Cisco 2500 Series

Product Overview

The Cisco 2500 series routers provide a variety of models designed for branch office and remote site environments. These routers are typically fixed configuration with at least two of the following interfaces:

Cisco 2500 routers come with Flash EPROM technology for simplified software maintenance. These systems support a variety of Cisco IOS software feature sets, so you can choose a feature set that supports your specific protocol environment. The software feature sets range from an IP and bridging-only to the full array of Cisco's software functionality, including APPN and RMON.

Mission-specific models contain less memory and less hardware functionality to support a subset of protocols. Each mission-specific model can be upgraded to full router capability by downloading a new Cisco IOS software feature set and, if necessary, adding memory.

Cisco 2500 series models can be divided into the following categories:

Standard Features

All the Cisco 2500 series models support the features listed in Table 10-24.

Hardware

The Cisco 2500 series routers are discussed in the following sections:

Memory Options

All Cisco 2500 models include a minimum of 8 MB of Flash memory, except for the mission-specific routers which include 4 MB of Flash memory. However, depending on the Cisco IOS software release shipped with the system, it might require more memory. Additional Flash memory can be purchased to allow for dual banking or potential future code growth.

There are two types of DRAM memory in the Cisco 2500 series routers: primary and shared (packet). Primary memory is used to store the operating configuration, routing tables, caches, and queues. Shared memory is used to store incoming and outgoing packets. In Table 10-26, the physical configuration column lists the amount of DRAM SIMM memory supported. The system usage column lists how the system allocates the total DRAM memory installed.

Mission-Specific Routers

Mission-specific routers are entry-level routers that are based on standard Cisco 2500 hardware. However, mission-specific routers contain less memory than standard models and run reduced software images designed for CFRAD, LAN FRAD, and ISDN applications. These reduced software images disable unused ports. Mission-specific routers can be upgraded to full standard-model functionality by purchasing additional software and memory.

The network interfaces for the Cisco 2500 series mission-specific routers are listed in Table 10-29.

Modular Routers

Models 2524 and 2525 provide LAN and WAN access in a low-cost modular router platform that can grow with your internetworking needs. The Cisco 2524 offers an Ethernet (AUI or 10BaseT) LAN connection, and the Cisco 2525 offers a Token Ring (STP or UTP) LAN connection. Both routers can accommodate up to three WAN modules--two synchronous serial and one ISDN.

The choice of synchronous serial WAN modules is as follows:

Note The five-in-one synchronous serial WAN module gets its name from the five types of signaling it supports, which include the following: EIA/TIA-232, EIA/TIA-449, V.35, X.21, and EIA-530. You can order a DB-60 shielded serial transition cable. The router end of the cable has a DB-60 connector; the other end of the cable has the appropriate connector for the standard interface you specify.

The choice of ISDN WAN modules is as follows:

The ISDN WAN modules are keyed so that you cannot insert them into the synchronous serial WAN slots. A blank slot cover is installed over unused slots.

Figure 10-69 shows the rear view of the Cisco 2524 router, and Figure 10-70 shows the rear view of the Cisco 2525 router.

Figure 10-71 through Figure 10-76 show the WAN modules. Figure 10-77 shows the blank slot cover.

1 Mission-specific router. Mission-specific routers are based on standard Cisco 2500 hardware, but they contain less memory and run reduced Cisco IOS images that disable unused ports and support a subset of protocols. By adding software, and possibly memory, mission-specific routers can be upgraded to full standard router functionality.
2 See the "Access Servers" chapter later in this catalog, for more information.

Software

The Cisco IOS software available for the Cisco 2500 series router is described in the following sections:

The Cisco 2500 series routers support the following software releases:

Note that entry-level, mission-specific models are not listed because software is included with the hardware. For more information about mission-specific software, refer to Table 10-38.

Software Feature Sets

The Cisco 2500 series offers the following types of feature sets:

Note Cisco IOS images with 40-bit Data Encryption Standard (DES) support may legally be distributed to any party eligible to receive Cisco IOS software. 40-bit DES is not a cryptographically strong solution so its use should be carefully evaluated.

Cisco IOS images with 56-bit DES are possibly subject to export and/or import controls and may have a limited distribution. For more information, contact your sales representative or distributor, or visit CCO at http://www.cisco.com/wwl/export/encrypt.html , or send e-mail to export@cisco.com.

The Cisco IOS feature set tables use the following conventions to identify features:

Software Feature Packs

Software feature packs consist of CD-ROMs that contain Cisco IOS software feature set images and a Windows 95 application, which loads the images onto a router.

Software feature packs are available for most of the Cisco IOS Release 11.2 feature set images listed in Table 14. Table 10-34 lists the product numbers for feature sets and feature packs available in Cisco IOS Release 11.2.

For more information about software feature packs, see the section "Cisco IOS Feature Packs" in the chapter "Cisco IOS Software," earlier in the catalog.

Note You can also order a Cisco IOS software feature pack for the standard versions of the models listed above.

The RMON MIB (RFC 1757) allows you to monitor all nodes and their interaction on a LAN segment. Standard Cisco IOS Release 11.1 feature sets provide support for the RMON alarm and event groups only. If you prefer more network management support, you can order an enhanced RMON feature set that includes full support for the following nine groups: statistics, history, alarms, hosts, hostTopN, matrix, filter, capture, and events. Table 10-33 describes the contents of the enhanced IP/RMON, IP/IPX/RMON, and Enterprise/RMON feature sets.

In Cisco IOS Release 11.2, the feature RMON full is available in the Plus feature sets.

1 In Cisco IOS Release 11.2 and later releases, RMON is available in the Plus feature sets. It is listed as "RMON full" in the appropriate hardware platform tables. RMON is available only as a separate feature set in Cisco IOS Release 11.1.
2 See the category "IBM Support" for information about source-route bridging (SRB).
3 ISDN support includes calling line identification (ANI), X.25 over the B channel, ISDN subaddressing, and applicable WAN optimization features.
4 PPP includes support for LAN protocols supported by the feature set, address negotiation, PAP and CHAP authentication, PPP compression, and Multilink PPP.
5 X.25 Includes X.25 switching.
6 IPX header compression (RFC 1553) is available in the feature sets that support IPX with Cisco IOS Release 11.1(1) and later releases.
7 X.25 and Frame Relay payload compression.
8 The RMON events and alarms groups are supported for all interfaces; however, the full nine groups are supported for Ethernet interfaces only. For security reasons, packet capture only captures packet headers, not data.
9 MAC security for hubs applies to the following Cisco 2500 series Ethernet hubs: 2505, 2507, and 2516.
10 IBM support is available as a separate Cisco IOS feature set with the IBM base option: IP/IBM base, IP/IPX//IBM base.

12 NASI is available in Cisco IOS Release 11.1(2) and later releases.
13 LAT terminal services are available for Cisco 2500 series access servers; not routers. Use of LAT requires a terminal   license. For more details, see the "LAT Terminal License" section in the "Access Servers" chapter later in the catalog.

Software Product Numbers

This section describes the software product numbers for the Cisco 2500 series. Table 10-35 lists the software feature set and feature pack product numbers and minimum memory requirements for Cisco IOS Release 11.2. Table 10-34 lists the software feature set product numbers and minimum memory requirements for Cisco IOS Releases 11.1 and 11.0.

Note All Cisco 2500 series models include a minimum of 8 MB of Flash memory; however, depending on the Cisco IOS release feature set or feature pack that you order with the system, it might require more memory. Refer to Table 10-34 and Table 10-35 for the minimum Flash memory required for each feature set.

The minimum memory requirements listed were chosen for typical branch and remote office applications. If your network is very large, using complex routing protocols, or using RMON, you might need more memory. Configuration analysis and testing are encouraged.

Cisco IOS Feature Set Upgrades

Cisco IOS feature set upgrades are easy to order for Cisco 2500 series routers. The following is an example:

You have a Cisco 2505 router running the Cisco IOS Release 11.2 IP Routing feature set. You want to upgrade to the Cisco IOS Release 11.2 Enterprise Plus feature set. You are crossing two feature sets: one to get from IP to Enterprise, and one to get to the Plus feature set. To complete the upgrade, use the following guidelines:

Feature sets for Cisco IOS Release 11.2 can be upgraded as described in Table 10-36.

Feature sets for Cisco IOS Releases 11.1 and 11.0 can be upgraded as described in Table 10-37. To order an upgrade, you must use two product numbers; one represents the upgrade license, and the other represents the software. For example, to upgrade from an IP feature set to an IP feature set with IBM base functionality, order product number FRAP-CCS= (the upgrade license) and SW25CS-xx.x.x= (the software). To upgrade to a feature set with APPN, you must first purchase the upgrade license for the desired feature set and then purchase the upgrade license and upgrade software for the APPN feature set.
