First, enable lldp globally:
lldp run
Then also configre lldp on each interface. The native vlan should be vlan 1 (data) and the voice vlan should be 2, like this:
interface GigabitEthernet1/0/3
switchport access vlan 1
switchport mode access
switchport voice vlan 2
ip dhcp relay information check-reply
spanning-tree portfast
lldp transmit
lldp receive
Cisco and many other Network companies, like HP use PowerPC processors in their layer 2 and layer 3 switches. Newer versions like the Cisco 2960X switch uses an APM86392 600MHz dual core by AppliedMicro. This processor has been used for many of the new switch series in different varities.
The larger and more hardcore layer 2/3 switches/routers uses the new Cavium 6230 800 MHz 4-core CPU, like the 3650 and 3850 series.
When you change to data center switches, the CPU is typically an Intel(R) Xeon(R) CPU. This is normally on the Nexus series. The Cisco ASR 9000 Series Aggregation Services Routers uses an RSP processor. The RSP880 has 8 cores, 1.9 GHz while RSP880-LT has 4 cores, 2.4Ghz.
I've probably forgotten a lot, but there's a big difference in CPU's depending on what the purpose of the switch or router is. Also, like the consumer market, CPU's for the commercial market is constantly being upgraded. A change in the CPU architecture takes time and therefore sometimes the same CPU will be used for generations.
In Cisco, to find out what your switch or router CPU is, you can search for the Data Sheet on google for your specific model. If you have CLI access typically show version
will give you information about the CPU on the switch or router.

I don't know how to show it in the CLI, it's not in the output of
show interfaces verbose
orshow port-statistics
afaik...Another option could be to query it using SNMP. Avaya supports the IF-MIB, and the ifTable entries contain an
ifLastChange
value (.1.3.6.1.2.1.2.2.1.9):Note that this value is in "ticks", or 1/100ths of a second.
