I have a 2801 running the very latest 12.4(22)T (can't remember what feature set) that is connected directly on a 10/100 Ethernet interface to an ASA5510 (running 7.2(4) - its actually FastEthernet0/0 connected to Ethernet0/2. They are currently configured for auto-speed & duplex and show they have negotiated 100/Full at both ends(I have tried hard-coding 100/Full at both ends and the behaviour is exactly the same).
On the 2801 every 30-seconds there is a message logged that says the FastEthernet0/0 interface changed state to up:
003868: Nov 25 23:26:07.929 GMT: %LINK-3-UPDOWN: Interface FastEthernet0/0, changed state to up
003869: Nov 25 23:26:37.926 GMT: %LINK-3-UPDOWN: Interface FastEthernet0/0, changed state to up
There appear to be no errors on the interface and it seems to be operating OK, however this message is a slightly worrying. The ASA is not reporting any equivalent errors.
Does anyone know why this is and how to resolve it? The 2801 when connected to a Catalyst 3560 using the same interface didn't generate the messages.
