Cisco ICS 7750 Traps

Cisco ICS 7750 ASI cards, MRP cards, and the SSP card can generate traps such as the following:

•coldStart—Indicates power-up reset of a card.

•warmStart—Indicates that software running on a card has been upgraded or that the card has been reset.

•linkDown—Indicates that a port changed to a suspended or disabled state due to a secure address violation (mismatch or duplication), network connection error (such as a loss of Link Beat or a jabber error), or an explicit management disable action.

•linkUp—Indicates that a port has changed from a suspended or disabled state to the enabled state.

•authenticationFailure—Indicates that an SNMP message has been received that is not properly authenticated; that is, the message is not accompanied by a valid community string.

•addressViolation—Indicates that an address violation has been detected on a secured port.

•broadcastStorm—Indicates that the number of broadcast packets received in a second from a port is higher than the broadcast threshold.

Understanding Community Strings

SNMP community strings authenticate access to MIB objects and function as embedded passwords.

The Cisco ICS 7750 uses a base community string, to which the string @SLOTnumber can be appended to form a composite community string:

base community string@SLOTnumber

where

•Base community string represents the get or set community string. For get (read-only) requests, the community string, or password, has a default ASCII value of public. For set (read-write) requests, the community string has a default value of changeme.
