Are there any troubleshooting commands that can be performed to rule out a transceiver issue? In the past I typically start at one end of the link and start replacing sfp's and fiber optic patch cords until the CRC errors stop incrementing.
can anyone point me in the direction of a SIMPLE VLC multicast lab? I don't even mind if it's 1 or 2 routers, a VM and loopback I just want to be able to stream from one end to the next and test out commands afterwards
Hello, I have the following messages in my debug ip nat : *Nov 16 14:22:21.711: NAT: s=10.39.226.100->10.233.1.3, d=10.233.90.100 [11047] *Nov 16 14:22:22.075: NAT*: s=10.39.226.100->10.233.1.3, d=10.233.90.100 [11048] Everything works fine but I...

Resolved! ISR 4331 SFP
Hi Folks Wonder if you could help have an ISR 4331 with an SFP (SFP-GB-GE-T) in interface G0/0/2. It is set for auto negotiation and negotiates to 100M/Full duplex to an ADVA NTE. Although the interface comes up I am seeing CRC errors. The circuit th...
