The default value for the interval between SNMP LLDP trap notifications is 5 seconds. You change this
interval for the entire switch for LLDP traps using the following command:
configure lldp snmp-notification-interval <seconds>
Configuring Optional TLV Advertisements
By default, all optional TLVs are not added to the LLDPDU, or not advertised.
You can add optional TLVs to the LLDPDU but be aware that the total LLDPDU cannot exceed 1500
bytes, including the mandatory TLVs. Any optional added TLVs that exceed the 1500-byte limit are
dropped. You can see if you have dropped TLVs from your LLDPDU by referring to the EMS log or by
issuing the
show lldp statistics
command.
NOTE
Extreme Networks recommends that you advertise only one or two VLANS on specified ports to avoid dropping TLVs
from the LLDPDU.
You configure LLDP ports to advertise any of the following optional TLVs:
●
Port description TLV
●
System name TLV
●
System capabilities TLV
●
Management address TLV
●
VLAN name TLV (repeatable TLVs)
●
Port VLAN ID TLV
●
Port and protocol VLAN ID TLV (repeatable TLVs)
●
MAC/PHY configuration/status TLV
●
Power via MDI TLV
●
Link aggregation TLV
●
Maximum frame size TLV
Refer to “Optional TLVs” on page 152 for complete information on each optional TLV.
To advertise the optional port description information, issue the following command:
configure lldp ports [all | <port_list>] [advertise | no-advertise] port-description
To advertise the system name, issue the following command:
configure lldp ports [all | <port_list>] [advertise | no-advertise] system-name
To advertise the system capabilities, issue the following command:
configure lldp ports [all | <port_list>] [advertise | no-advertise] system-
capabilities
