Intel 811, 813 Caveats

Release Notes for the Cisco811 and 813 Routers forCisco IOSRelease 12.1(2)XF

78-11070-02, Rev. H0

System Requirements

A Phone Mate answering machine model 9200 failed to recognize the ringing signal sent by AMD R79

ringing SLIC. This was confirmed by testing against Phone Mate model 3750 and newer model9300.

Cisco 800 series routers do not support PPP protocol over Frame Relay.

Cisco 800 series routers now support the Terminal Access Controller Access Control System Plus

(TACACS+) protocol through Telnet. TACACS+ is a Cisco proprietary authentication protocol that

provides remote access authentication and related network security services, such as event logging.

User passwords are administered in acentral database, rather than in individual routers. TACACS+ also

supports separate modular authentication, authorization, and accounting (AAA) facilities that are

configured at individual routers.

For information on how to configure TACACS+, refer to the “Configuring TACACS+” chapter in the

Security Configuration Guide. For information on TACACS+ commands, refer to the “TACACS,

Extended TACACS, and TACACS+ Commands” chapter in theSecurity Command Reference.

Cisco 800 series routers do not support the following protocols:

•TACACS,an older access protocol now deprecated by Cisco, or Extended TACACS,an extension

to the TACACS protocol.

•RADIUS or Kerberos protocols.

This release supports the setting of 1 only, for the ROM monitorset stop-bits parameter.
