lldp non-strict-med-tlv-order-check
Overview
Use this command to enable non-strict order checking for LLDP-MED
advertisements it receives. That is, use this command to enable LLDP to receive
and store TLVs from LLDP-MED advertisements even if they do not use standard
TLV order.
Use the
no
variant of this command to disable non-strict order checking for
LLDP-MED advertisements, that is, to set strict TLV order checking, so that LLDP
discards any LLDP-MED TLVs that occur before the LLDP-MED Capabilities TLV in
an advertisement.
Syntax
lldp non-strict-med-tlv-order-check
no lldp non-strict-med-tlv-order-check
Default
By default TLV non-strict order checking for LLDP-MED advertisements is disabled.
That is, strict order checking is applied to LLDP-MED advertisements, according to
ANSI/TIA-1057, and LLDP-MED TLVs in non-standard order are discarded.
Mode
Global Configuration
Usage
The ANSI/TIA-1057 specifies standard order for TLVs in LLDP-MED advertisements,
and specifies that if LLDP receives LLDP advertisements with non-standard
LLDP-MED TLV order, the TLVs in non-standard order should be discarded. This
implementation of LLDP-MED follows the standard: it transmits TLVs in the
standard order, and by default discards LLDP-MED TLVs that occur before the
LLDP-MED Capabilities TLV in an advertisement. However, some implementations
of LLDP transmit LLDP-MED advertisements with non-standard TLV order. To
receive and store the data from these non-standard advertisements, enable
non-strict order checking for LLDP-MED advertisements using this command.
Examples
To enable strict TLV order checking, use the commands:
awplus#
configure terminal
awplus(config)#
lldp tlv-order-check
To disable strict TLV order checking, use the commands:
awplus#
configure terminal
awplus(config)#
no lldp tlv-order-check
