DHCP Problem after update to 8.10.0.12

  • 1.  DHCP Problem after update to 8.10.0.12

    Posted 3 days ago

    Hi,

    I am facing an problem after  I did an update from 8.6.0.22 to 8.10.0.12. We are using an mobility condutor environment with about 90 mobility gateways.

    I did this update in the last few weeks on almost 50 mobility gateways. Last night I did the remaining an this causes an issue.

    Internal DHCP server is not working any more on these last machines.

    Show ip int brief tells, that the problem vlan is up but protocol is down. Don't know if it is just a symptom beacuse users did not get an IP so  there are no users in vlan.

    I created a new vlan with dhcp and it is working. But i cannot change ip settings for not working vlan that easy.

    Any idea? Anybody had similar problems?

    Such issues, with this level of detail, are better to be resolved through your Aruba partner or TAC.

    If you have a VLAN without any ports (or associated client) to it, it will remain down, unless you put the 'operstate up' command on the VLAN interface. Have seen issues where it takes a while when a client connects for the VLAN to become active, and not sure how the dhcp server handles VLANs going up/down. Note that the DHCP server in the controller should only be used if there is no better solution in place. External servers (as well external routing, so not on the gw/controller) is preferred in most cases.
