Error Message on 4006 CAT OS Switch.

[utawakevou]

I got this message coming up on console. Can somebody explain to me what does this mean. Recently weve been experiencing intemmitent network drops on our Network.

--More--2004 Jul 15 08:25:38 %SYS-4-P2_WARN: 1/Tag 0 on packet from 00:50:8b:5d:29:7a

Also when I do a "show cam" on my 4006 switch I couldnt get the mac-address above.

Please help

This is really helpful. Now I understand that problem. Thank you.However I couldnt pinpoint exactly the source port. May be the reason being the set-up of the logging messages. All I got is this:

2004 Jul 15 13:37:24 %SYS-4-P2_WARN: 1/Tag 0 on packet from 00:50:8b:5d:29:7a p1

2004 Jul 15 13:49:22 %SYS-4-P2_WARN: 1/Tag 0 on packet from 00:50:8b:5d:29:7a p1

2004 Jul 15 14:49:14 %SYS-4-P2_WARN: 1/Tag 0 on packet from 00:50:8b:5d:29:7a p1

How do I set-up my logging messages so that I can see the complete message to determine the source port ?

Please I need this to eliminate this problem.

There is no config to see the complete message. Probably your telnet client is truncating them. Use a different telnet client or issue a sh logging buffer

Thanks. I manage to get the complete message. Change my telnet client to Hyperterminal. I was using Smarterm before. Found out that the source port of that error is where one of our main routers is connected to.

The switch port is on VLAN 1. Log into the router and do a "show vlan-switch" and come up with this result:

VLAN Name Status Ports

---- -------------------------------- --------- -------------------------------

1 default active

1002 fddi-default active

1003 token-ring-default active

1004 fddinet-default active

1005 trnet-default active

VLAN Type SAID MTU Parent RingNo BridgeNo Stp BrdgMode Trans1 Trans2

---- ----- ---------- ----- ------ ------ -------- ---- -------- ------ ------

1 enet 100001 1500 - - - - - 1002 1003

1002 fddi 101002 1500 - - - - - 1 1003

1003 tr 101003 1500 1005 0 - - srb 1 1002

1004 fdnet 101004 1500 - - 1 ibm - 0 0

1005 trnet 101005 1500 - - 1 ibm - 0 0

Log into our 4006 switch and found out this was configured on my switch:

set vlan 1002 name fddi-default type fddi mtu 1500 said 101002 state active

set vlan 1004 name fddinet-default type fddinet mtu 1500 said 101004 state acti

set vlan 1005 name trbrf-default type trbrf mtu 4472 said 101005 state active b

set vlan 1

set vlan 1003 name trcrf-default type trcrf mtu 4472 said 101003 state active p

set vlan 1002 translation 1 translation 1003

set vlan 1003 translation 1 translation 1002

The router was connected to port 2/2 of the 4006 switch and that is the source port of that error message.

I believe I have to set up the port 2/2 on the switch to be trunk mode. By the way we dont have VLAN's on our network. Just using the default VLAN

Any ideas
