Hello Everyone,
We had an incident on our network last night where a serial interface went
down because the frame relay circuit DLCI was deleted. Here's the text:
May 31 03:41:32 CDT: %LINEPROTO-5-UPDOWN: Line protocol on Interface
Serial0/0, changed state to down
May 31 03:41:34 CDT: %LINK-3-UPDOWN: Interface Serial0/0, changed state to
down
May 31 03:41:34 CDT: %FR-5-DLCICHANGE: Interface Serial0/0 - DLCI 500 state
changed to DELETED
May 31 03:41:34 CDT: %LINEPROTO-5-UPDOWN: Line protocol on Interface
Serial0/0.1, changed state to down
May 31 03:56:54 CDT: %LINEPROTO-5-UPDOWN: Line protocol on Interface
Serial0/0, changed state to up
May 31 03:56:55 CDT: %LINK-3-UPDOWN: Interface Serial0/0, changed state to
up
May 31 03:56:55 CDT: %FR-5-DLCICHANGE: Interface Serial0/0 - DLCI 500 state
changed to ACTIVE
May 31 03:56:55 CDT: %LINEPROTO-5-UPDOWN: Line protocol on Interface
Serial0/0.1, changed state to up
So NetView was able to ping the associated IP address because it also exists
on the FastEthernet interface. The event viewer did show corresponding
Cisco_Link_Down and Cisco_Link_Up traps. So here are my questions:
1) Do I have to setup SNMP polling in the seed file for NetView to use SNMP
to query the interface?
2) How does NetView know this is an unnumbered interface?
3) I can create a ruleset to create a critical event to be forwarded to
Tivoli. Can I use the set state node in a ruleset to change the color of the
router object to red (Critical)?
