Important Notes

Here, the command fair-queue 64 limits the number of conversations to 64, and the command

queue-limit 64 sets the discard threshold to 64. The command hold-queue 64 out limits the maximum

number of output packets to 64.

Failure to configure the above parameters may cause the router to display out-of-memory messages

when a large amount of mixed traffic is transmitted from ethernet to ATM.

Cisco 800 Series Router Clock—CSCdp09409

To run IPSec successfully, the Cisco 800 series router clock needs to be set accurately. Cisco 800 series

router clocks are set and maintained using Simple Network Time Protocol (SNTP). For best results, set

up a Network Time Protocol (NTP) server to periodically send time information messages to Cisco 800

series routers. See the SNTP configuration and command reference documentation for configuration

instructions. If you do not have an NTP server, you must reset the Cisco 800 series router clock using

the clock set command each time you restart the router.

The SNTP configuration documentation is available in the chapter "Monitoring the Router and

Network" volume of the Configuration Fundamentals Configuration Guide in the Cisco IOS

documentation set. The SNTP command reference documentation is available in the chapter "Router and

Network Monitoring Commands" in the "System Management Commands" volume of the

Configuration Fundamentals Command Reference manual of the Cisco IOS documentation set.

Cisco 800 Series Router Enhancements

Cisco 800 series routers support the following features. For more information about these features, see

the Cisco IOS documentation set.

Release Notes for the Cisco 800 Series Routers for Cisco IOS Release 12.1(5)YC

Hot Standby Routing Protocol (HSRP), which creates a Hot Standby router group with a lead router

that services all packets sent to the Hot Standby address. The lead router is monitored by other

routers in the group. If it fails, one of these standby routers inherits the lead position and the Hot

Standby group address.

Service Assurance Agent (SAA), which is both an enhancement to and a new name for the Response

Time Reporter (RTR) feature that was introduced in Cisco IOS release 11.2. This feature allows you

to monitor network performance by measuring key Service Level Agreement (SLA) metrics, such

as response time, network resources, availability, jitter, connect time, packet loss, and application

performance.

Triple Data Encryption Standard (3DES), based on the standard cryptographic algorithm developed

by the U.S. National Bureau of Standards.

X.28, X.29, and X.3 emulation for Packet Assembler/Disassembler (PAD), the standard user

interface between the data terminal equipment and PAD.

Frame Relay Inverse Address Resolution Protocol (ARP), which enables a station to request a

protocol address corresponding to a given hardware address.

Frame Relay support for a permanent virtual circuit (PVC) saves bandwidth associated with circuit

establishment and tear down in situations where certain virtual circuits must exist all the time.
