Port Field Descriptions

Use the data in the following table to use the Port tab.

Name

Description

PortNum

Specifies the port number. This is a read-only cell.

AdminStatus

Specifies the administrative status of the port. The options are:

  • txOnly: LLDP frames are only transmitted on this port.

  • rxOnly: LLDP frames are only received on this port.

  • txAndRx: LLDP frames are transmitted and received on this port.

  • disabled: LLDP frames are neither transmitted or received on this port. Any information received on this port from remote systems before this is disabled, ages out.

The default is disabled.

NotificationEnable

Specifies whether the port is enabled or disabled for notifications.

  • true: indicates that the notifications are enabled.

  • false: indicates that the notifications are disabled.

The default is false.

TLVsTxEnable

Specifies the set of TLVs whose transmission using LLDP is always allowed by network management.

The following list describes the TLV types:

  • portDesc — indicates that the Port Description TLV is transmitted.

  • sysName — indicates that the System Name TLV. is transmitted.

  • sysDesc — indicates that the System Description TLV. is transmitted.

  • sysCap — indicates that the System Capabilities TLV. is transmitted.

The default is an empty set of TLVs.

CdpAdminState

Specifies the CDP administrative status of the port. Configure this field to true to enable the Industry Standard Discovery Protocol (ISDP) on a port. ISDP is CDP-compatible.

  • true: indicates CDP is enabled.

  • false: indicates CDP is disabled.

The default is false.

If CDP is enabled, the interface accepts only CDP packets. Similarly, if CDP is disabled but LLDP is enabled, the interface accepts only LLDP packets. To switch a port from CDP mode to LLDP mode, the LLDP status on that port must be txAndRx.

CapSupported(med)

Specifies the LLDP-MED capabilities supported.

The default is enabled.
