Installing or Enabling a DHCP Server on Other SPE310s or Other Servers
Do not install or enable a DHCP server on the SPE310 that is running System
Manager. You can install or configure DHCP on an external server, provided that
• The external DHCP server is configured to not respond to DHCP or BOOTP
requests from Cisco ICS 7750 cards
• If ICS System Manager is providing DHCP services to IP phones or external
DHCP clients, the external DHCP server should not be configured to respond
to these hosts
• The DHCP IP address ranges of the external DHCP server must not conflict
with the DHCP or BOOTP IP address ranges in use by ICS System Manager
Note If you are using a DHCP server on an external server, consult your DHCP server
documentation for additional DHCP configuration guidelines.
SSP Error Messages
If you are using Cisco IOS 12.0(5)WC2b on the SSP, and if you are monitoring
the system through a console connection to the SAP, error messages similar to the
following might be generated as the SSP boots:
% error opening tftp://255.255.255.255/cisconet.cfg (Time out)
% error opening tftp://255.255.255.255/router-confg (Time out)
% error opening tftp://255.255.255.255/ciscortr.cfg (Time out)
This is an expected condition. The system will continue to operate normally
without any external intervention.
Best Practices for Using the Cisco IOS CLI
ICS System Manager is designed to communicate with and to monitor the status
of all the components in the chassis. To enable ICS System Manager to perform
these functions, a configuration program (ICSConfig) guides you through the
configuration process. ICSConfig enables you to change key system parameters,
such as the IP addresses of system cards, passwords, destination for syslog
messages, and Simple Network Management Protocol (SNMP) community
strings.
