We're experiencing infrequent CRC/Jabber errors on a particular interface between 2 670v-48x switches. Switches are running code version 22.214.171.124 patch 1-18 at the moment. They run our iSCSI network.
Both ports connected together, 49-49 on each switch experience the errors, connected via pre terminated copper cable, Q+CR4_3m.
I have checked that the cable is not in the vicinity of electrical cables to try to rule out interference.
Would it simply be a bad cable/module on the cable that causes this? We've had to change this before so I'm concerned it may be the slot(s) in the switch(es) itself?
Any thoughts welcome :)
