HP A3100-8 v2 SI User Manual

To do… Use the command… Remarks
Set the number of LLDPDUs sent
each time fast LLDPDU transmission
is triggered
lldp fast-count count
Optional
3 by default
NOTE:
To ensure that the LLDP neighbors can receive LLDPDUs to update information about the current device
before it ages out, configure both the LLDPDU transmit interval and delay to be less than the TTL.
Setting an encapsulation format for LLDPDUs
LLDPDUs can be encapsulated in the following formats: Ethernet II or SNAP frames.
• With Ethernet II encapsulation configured, an LLDP port sends LLDPDUs in Ethernet II frames and
processes only incoming, Ethernet II encapsulated LLDPDUs.
• With SNAP encapsulation configured, an LLDP port sends LLDPDUs in SNAP frames and processes
only incoming, SNAP encapsulated LLDPDUs.
By default, Ethernet II frames encapsulate LLDPDUs. If the neighbor devices encapsulate LLDPDUs in
SNAP frames, configure the encapsulation format for LLDPDUs as SNAP to guarantee normal
communication with the neighbors.
Follow these steps to set the encapsulation format for LLDPDUs to SNAP:

format applies by default.
NOTE:
LLDP-CDP (Cisco Discovery Protocol) packets use only SNAP encapsulation.
Configuring CDP compatibility (available only on
the A3100 v2 EI)
NOTE:
• For more information about voice VLAN, see the chapter “Voice VLAN configuration.”
• The A3100 v2 SI Switch Series does not support voice VLAN and CDP-compatible LLDP configurations.
To make your device work with Cisco IP phones, you must enable CDP compatibility.
