Ports and Port Channel Commands

pnic

To modify the configuration of an Ethernet port or to create a port channel, use the pnic command. To set an Ethernet port to its default settings or to delete a port channel, use the no form of the command.

pnic name [ adminstatus { up | down } ] [ type { ethernet | port_channel } ] [ bond_mode { active-backup | balance-slb | balance-tcp } ] [ lacp_type { active | passive | off } ] [ member_of portchannel_name] [ trunks vlan_num] [ lldp { enabled | disabled } ]

no pnic name [ adminstatus] [ type] [ bond_mode] [ lacp_type] [ lldp] [ member_of portchannel_name]

Syntax Description

name

Specifies the name of the port.

adminstatus

Brings a port up or down administratively. Valid values are up and down.

type

Specifies the type of the port. Valid values are ethernet and port_channel. To create a port channel, you must specify the value as port_channel.

bond_mode

Specifies the bond mode for a port channel. Valid values are active-backup, balance-slb, and balance-tcp. Default is balance-tcp.

lacp_type

Specifies the LACP type for a port channel. Valid values are off, active, and passive. Default is off.

member_of portchannel_name

Adds the port to the specified port channel.

trunks vlan_num

Specifies the VLANs. Valid range is from 1 to 4096. Default is VLAN 1. Enter VLANs separated by commas, VLAN ranges separated by dashes, or a combination of both.

lldp

Enables or disables LLDP on a port. Valid values are enable and disable. Default is disable.
