Last night the link between two of our routers was done for a while, the link is a 100mbit leased line. Strangely no logs were commited from the router to highlight this problem, e.g that the line protocol is down, could someone point out a reason why? The log entry config on the router is:
logging history debugging
logging facility local5
My other question is related to this downed link. I have OSPF and RIP running between the two routers. Is there a way for me to find out information about how long the adhjacency has been formed, thereby getting an idea as to when the link came up? Is it also possible to tell when this relationship broke?
have you enabled SNMP trap to trap link status of interfaces? if not, then whenever link goes up/down, message will not be recorded in log buffer.
you can configure "log-adjacency-changes" command under OSPF process. whenver OSPF neighbor goes down, it will generate a log which will be stored in the log buffer as when OSPF neighbor went down and when it came up.

interface we use the VLAN tag to demultiplex the VLANs. The switch needs
