IP phones (avaya) hang at discover mode and unable to communicate to call manager server , is configuring lldp on extreme switch access ports mandatory ?

Are below lines enough:

code:

enable lldp ports


code:

configure lldp port advertise vendor-specific med capabilities


code:

configure lldp port advertise vendor-specific dot1 vlan-name vlan


code:

configure lldp transmit-interval 5


Are above commands for access ports only on which ip phones connect?

Please take a look at this article and see if you can prioritize the voice traffic in the network. https://gtacknowledge.extremenetworks.com/articles/How_To/Configuring-QOS-profiles-and-verify-QOS-is-working I am pointing to this article considering that there are no packet drops in the network. You might need to check the Voice traffic patch and see if the ports does not drop packets due to high traffic and then you can apply the QOS profile.
