lldp advertise max-frame-size

Advertises the maximum frame size capability of the port.
Syntax
lldp advertise max-frame-size ports { all | [ ethernet unit/slot/port [ to unit/slot/port ] ... ] }
no lldp advertise max-frame-size ports { all | [ ethernet unit/slot/port [ to unit/slot/port ] ... ] }
Command Default

The maximum frame size is automatically advertised when Link Layer Discovery Protocol (LLDP) is enabled on a global basis.

The maximum frame size is 1522 octets.

Parameters
ports
Advertises the maximum frame size for the specified ports.
all
Advertises the maximum frame size for all LLDP-capable ports.
ethernet unit/slot/port
Advertises the maximum frame size for a specific Ethernet port.
to stack-id/slot/port
Advertises the maximum frame size for a range of Ethernet ports.
Modes

Global configuration mode

Usage Guidelines

The maximum frame size TLV provides the maximum 802.3 frame size capability of the port. This value is expressed in octets and includes the four-octet Frame Check Sequence (FCS). The default maximum frame size is 1522. The advertised value may change if the aggregated-vlan or jumbo command is configured.

Note: On 48GC modules in nonjumbo mode, the maximum size of ping packets is 1486 bytes and the maximum frame size of tagged traffic is no larger than 1581 bytes.

You can specify a list of ports, separated by a space, or a range of ports, or you can combine lists and ranges.

The command cannot support LAG virtual interfaces. Attempting to configure them will have no effect.

The no form of the command disables the advertisement.

Examples

The following example enables the maximum frame size advertisement on a range of Ethernet ports.

device(config)# lldp advertise max-frame-size ports ethernet 1/1/4 to 1/1/12
