Cisco 2500 Series
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:
- Ethernet (AUI)
- 10BaseT Ethernet Hub
- Token Ring
- Synchronous Serial
- Asynchronous Serial
- ISDN BRI
All Cisco 2500 models include a minimum of 8 MB of Flash memory,
except for the mission-specific routers which include 4MB or 8MB of Flash memory
depending upon the Cisco IOS software release. 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.
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.
