Avaya phone can't get an ip from pool created on the Aggregation switch it is directly connected to access switch and when I show lldp on the access switch I see the Avaya phone assigned an ip for it although the phone doesn't take the ip address from the DHCP Server need assistance from the configuration to be reviewed from the access switch and aggregation switch
set system services dhcp-local-server group g80 interface irb.1280

Greetings! I have checked the configuration and the configuration looks good. Please check the below and see if it helps. Since you are seeing an IP address in the LLDP info, it would mean that the IP address is being offered by the switch.
1. Are you getting the IP address in the range configured on the aggregation switch? 2. Have you tried re-setting the Avaya phone? 3. What model of Aggregation/access layer switch are you using and what version?

I would suggest a packet capture on the access switch on one of the ports facing an Avaya phone. I have seen situations where the the address is assigned, but the end device send a release packet rejecting the IP address. I am not saying this is the situation, but is just an idea for further troubleshooting.
