DHCP Being assigneg on other Vlan
« on: February 09, 2017, 09:47:43 AM »
Issue: DHCP on vlan 69 it's being assigned on vlan 1104 "some times". When I reboot the computer or the port everything comes up fine.

Lots of information missing from the post, but let's consult my magic ball...

There's no Layer 3 or IP routing in this configuration, what's doing the routing for those VLANs? What's doing the DHCP relay? What port is the device in question connected to?

Looks like VLAN 69 is on the following ports:
 
vlan members 69 1/44-48,2/37


And it looks like ports 1/44-48 are an MLT trunk.... so the port you are using is 2/37?

What's the PVID on port 2/37?
 
vlan ports 2/ALL,3/1-21 pvid 1104


That's not good.. you have port 2/37 in VLAN 69 but the PVID is set to 1104... error, error, error.

Good Luck!

Sorry, you right info attached.
------------------------------------------------------------
The port 2/37 It's an experiment with "tagging".
------------------------------------------------------------
The IP stuff is being done by an ERS 8310. I haven't touched too much the config but only the trunks and some Vlan Member config since I got this job. In the txt attached.
--------------------------------------------------------------
I have to clean the config I know.  ;D
-------------------------------------
Thanks for your time dude!

*This morning the computer on the port 3/12 had the same issue, I rebooted the computer and done, WEIRD!*
