Hello Everyone,
I have coome accross a few sites that I see some unknown protocol drops on the internal interface connecting to the switch.
Code:
GigabitEthernet0/0 is up, line protocol is up
Hardware is PQ3_TSEC, address is e05f.b951.6120 (bia e05f.b951.6120)
Description: Data_LAN
MTU 1500 bytes, BW 100000 Kbit/sec, DLY 100 usec,
reliability 255/255, txload 20/255, rxload 20/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
Full-duplex, 100Mb/s, media type is unknown media type
output flow-control is unsupported, input flow-control is unsupported
ARP type: ARPA, ARP Timeout 04:00:00

I did some research on this.. some say it is a bug in the code. I checked cisco and they came up with nothing for this perticular issue. I have also read something about cdp causing this issue, but cdp is enabled on both interfaces (router and switch)
has anyone else had any problems/fixes for this issue?
Thankls
