Intermittent connection Catalyst 4006
I have a device connected to a Catalyst 4006. When i set the port to vlan 60 the connection is fine and never is intermittent. Although, when i change the port to vlan 100, the device loses connection after 6-7 minutes. It loses the connection then establishes connection every 6-7 minutes. Any suggestions why?
Connection is stable on vlan 60, intermittent on vlan 100

what does your log say? Any indication of spanning tree issues?
Vlan 100 has an access-list applied, but VLAN 60 does not
interface Vlan100
ip access-group 100 in <===
no ip redirects
>the device loses connection after 6-7 minutes
What, exactly is it connecting to, and using what port/protocol?

ASKER
Its connected to a device called Gold Box Multi protocol print server. Its pretty ancient, it only runs on 10/h. It connects to an embosser printer we use to print out ID cards.
Will an access-list cause intermittent connectivity?
I do not see any spantree issues, although i see these errors:

Any suggestions?
interesting, whats on ports 2/13-20? Anything? Whats on 2/19 2/20 2/1
7 2/18 2/16 2/15 2/13 2/14?
What port is the printer connected to?
Do you have a RED supervisor LED? any Port LED's flashing?
post the output of show nvramenv 1 or show env 1 here
When you show that a few times... does the invaildpktbuffercrc count increment rapidly?
Can we shutdown gigaport 15 to test?
how many free slots do you have on the 4006?

ASKER
The printer is not connected to that blade, its on 6/22. Nothing is connected to ports 2/13-20 and i have no more free slots.

ok what about slot 3... what does it look like... What CatOS are you using? I forget does the 4006 start numbering on slot 0, or slot 1?
ASKER
It starts with 1 and i'm using 8.4.6
Slot three is fine, all devices on that blade are working.

ok post the config for the port 6/22
As far as your log entries... check out this document:
http://www.cisco.com/warp/public/473/astro_45640.html
These log entries may not be related to your problem on 6/22 however they are a cause for concern if they indicate a faulty supervisor or line card.
I would be very interested in any log entries for 6/22.
Also, you say it's a multi protocol print server.. is this being reconfigured for the new net when you move it? It may need to have a new IPX/appletalk/IP config applied to it. can you print to it when you first move it and then it goes away, or does it go away without being able to print to it?

ASKER
all that i changed was the IP and vlan. how would i get log entries for 6/22?
if you are not syslogging, well then histroical data is gone. recreate this problem, but this time be conneccted to the switch and do a term mon to log the messages to a log file. then search for 6/22.
What I hear you saying is that you changed the vlan on the switch and the IP on the print server.. you didn't modify the appletalk or IPX settings.
When you say it loses connection, is it because the port goes into disable, or does the device stop responding?

the device stops responding. I'll do a steady ping -t then after about 7 minutes the printer cant be reached.
