we are using x440g2 switches connected to a vsp8600 and nac to assing dynamic vlans with isid to connected clients. this works most of the time except for our deployment net which is used to install new clients.
the deployment vlan switches from active to pending in “show fabric attach assignments”. the uplink-port on the x440g2 is still tagged with the vlan but the uplink-port on the vsp loses its vlan assignment. this happens only with the deployment vlan, every other vlan works as expected.
to repair the problem temporarily i execute “conf deployment add nsi 13621” on the x440g2 and the vlan gets active again. this only helps for a short time though.
what could be the reason for this? is there a way to debug the assignment problem any further? i don’t see anything about that vlan in the logs unfortunately. maybe this is only a timeout issue?
