Output field

Description

Port ID

Specifies the ID of the port to which the MACsec statistics apply.

TxUntagged Packets

Specifies the number of transmitted packets without the MAC security tag (SecTAG), with MACsec disabled on the interface.

TxTooLong Packets

Specifies the number of transmitted packets discarded because the packet length is greater than the Maximum Transmission Unit (MTU) of the Common Port interface.

RxUntagged Packets

Specifies the number of received packets without the SecTAG, with MACsec not operating in strict mode.

RxNoTag Packets

Specifies the number of received packets without the SecTAG, with MACsec operating in strict mode.

RxBadTag Packets

Specifies the number of received packets discarded with an invalid SecTAG, or with a zero value Packet Number (PN)/invalid Integrity Check Value (ICV).

RxUnknown SCIPackets

Specifies the number of packets received with an unknown Secure Channel Identifier (SCI) and with MACsec not operating in strict mode.

RxNoSCI Packets

Specifies the number of packets received with an unknown SCI and with MACsec operating in strict mode.

RxOverrun Packets

Specifies the number of packets discarded because the number of received packets exceeded the cryptographic performance capabilities.

Example

The following example displays MACsec statistics for a specific port.
