Good evening,

My LAN management guys are reporting that " interface is down with our

Cisco switch " . I have checked the log files on the Cisco switch and

I found the following errors:

23w5d: %LINEPROTO-5-UPDOWN: Line protocol on Interface

FastEthernet0/6, changed state to up

23w5d: %LINEPROTO-5-UPDOWN: Line protocol on Interface

FastEthernet0/6, changed state to down

23w5d: %LINEPROTO-5-UPDOWN: Line protocol on Interface

FastEthernet0/6, changed state to up

23w5d: %LINEPROTO-5-UPDOWN: Line protocol on Interface

FastEthernet0/6, changed state to down

23w5d: %LINK-3-UPDOWN: Interface FastEthernet0/6, changed state to

down

23w5d: %LINK-3-UPDOWN: Interface FastEthernet0/6, changed state to up

23w5d: %LINEPROTO-5-UPDOWN: Line protocol on Interface

FastEthernet0/6, changed state to up

23w5d: %LINEPROTO-5-UPDOWN: Line protocol on Interface

FastEthernet0/6, changed state to down

23w5d: %LINEPROTO-5-UPDOWN: Line protocol on Interface

FastEthernet0/6, changed state to up

23w5d: %LINEPROTO-5-UPDOWN: Line protocol on Interface

FastEthernet0/6, changed state to down

23w5d: %LINK-3-UPDOWN: Interface FastEthernet0/6, changed state to

down

23w5d: %LINK-3-UPDOWN: Interface FastEthernet0/6, changed state to up

The interface is down for few seconds and comes up again multiple

times.

Any ideas? Cheers, Rob

      Bad or loose cable? Invalid settings (duplex mismatch or something the like)?

      I have some nodes which do this when they reboot. First, etherenet comes up

      "default", then the powerup script defines the ethernet port and the port

      temporarily goes down, then as the OS (VMS in my case) comes up, at one point,

      it takes over the ethernet port and it also goes down for a second or two.

      no logging event addr-flap

      carrier-delay 10

      Will help. It basically tells the switch to wait 10 seconds before declaring

      that the ethernet link is down. The first one reduces the number of syslog

      messages being issued.

      Sorry about that . addr-flap doesn't seem to work. And I can't find a reference

      for it either (although my switch says it supports it.

      SWITCH1(config-if)#logging event ?

      addr-flap Enable and Disable Address Flap messages

      link-status UPDOWN and CHANGE messages

      subif-link-status Sub-interface UPDOWN and CHANGE messages

      Obviously, link-status is the one to really remove it. It seems to generate 2

      messages (LINEPROTO-5 and LINK-3 messages) whenever the link changes.
