node-identifier { mac | sysname | user-defined node-identifier }: Specifies access

node identifier. By default, the node MAC address is used as the node identifier.

z mac indicates using MAC address as the node identifier.

z sysname indicates using the device name of a node as the node identifier.

z user-defined node-identifier indicates using a specified character string as the

node identifier, in which node-identifier is a string with 1 to 50 characters.

Description

Use the dhcp-snooping information format command to specify the padding format

for Option 82.

Use the undo dhcp-snooping information format command to restore the default

padding format.

By default, the padding format for Option 82 is normal.

Note that when you use the undo dhcp-snooping information format command, if

the verbose node-identifier argument is not specified, the padding format will be

restored to normal; if the verbose node-identifier argument is specified, the padding

format will be restored to verbose with MAC address as the node identifier.
