%DTP-4-PKTQFULL:DTP internal queue

Unanswered Question
Oct 19th, 2007

Anyone know what tha above may mean? It is from a catos switch running ancient SW, and the error message decoder suggests contacting support. The SW age means no TAC, but it would be nice to have a clue.

The network is also poorly designed - everything in VLAN1, blade servers via cheap switches, a right hodgepodge and no resilient links...

I have this problem too.
