show virtual-chassis vc-port statistics

fpcnumber

ID of the Virtual Chassis member. The FPC number is the same as the member ID.

All levels

Interface

VCP interface name. Unlike network interface names, a VCP interface does not include a slot number (member ID).

• The dedicated VCPs are vcp-0 and vcp-1.
• Ports internal to the VCP subsystem have names corresponding to the PIC and port number. For example, 0/24 indicates internal onboard port 24, and 1/26 indicates internal uplink module port 26.

brief

Input Octets/Packets

Total number of octets and packets received on the VCP interface.

brief member none

Output Octets/Packets

Total number of octets and packets transmitted on the VCP interface.

brief member none

master: number

Member ID of the Virtual Chassis master.

All levels

Port

VCP for which RX (Receive) statistics,TX (Transmit) statistics, or both are reported by the VCP subsystem during a sampling interval—since the statistics counter was last cleared.

detail extensive

Total octets

Total number of octets received and transmitted on the VCP interface.

detail extensive

Total packets

Total number of packets received and transmitted on the VCP interface.

detail extensive

Unicast packets

Number of unicast packets received and transmitted on the VCP interface.

detail extensive

Broadcast packets

Number of broadcast packets received and transmitted on the VCP interface.

detail extensive

Multicast packets

Number of multicast packets received and transmitted on the VCP interface.

detail extensive

MAC control frames

Number of media access control (MAC) control frames received and transmitted on the VCP interface.

detail extensive

CRC alignment errors

Number of packets received on the VCP interface that had a length—excluding framing bits, but including frame check sequence (FCS) octets—of between 64 and 1518 octets, inclusive, and had one of the following errors:

• Invalid FCS with an integral number of octets (FCS error)
• Invalid FCS with a nonintegral number of octets (alignment error)

detail extensive

Oversize packets

Number of packets received on the VCP interface that were longer than 1518 octets (excluding framing bits, but including FCS octets) but were otherwise well formed.

detail extensive

Undersize packets

Number of packets received on the VCP interface that were shorter than 64 octets (excluding framing bits but including FCS octets) and were otherwise well formed..

detail extensive

Jabber packets

Number of packets received on the VCP interface that were longer than 1518 octets—excluding framing bits, but including FCS octets—and that had either an FCS error or an alignment error.

Note: This definition of jabber is different from the definition in IEEE-802.3 section 8.2.1.5 (10Base5) and section 10.3.1.4 (10Base2). These documents define jabber as the condition in which any packet exceeds 20 ms. The allowed range to detect jabber is between 20 ms and 150 ms.

detail extensive

Fragments received

Number of packets received on the VCP interface that were shorter than 64 octets (excluding framing bits, but including FCS octets), and had either an FCS error or an alignment error.

Fragment frames normally increment because both runts (which are normal occurrences caused by collisions) and noise hits are counted.

detail extensive

Ifout errors

Number of outbound packets received on the VCP interface that could not be transmitted because of errors.

detail extensive

Packet drop events

Number of outbound packets received on the VCP interface that were dropped, rather than being encapsulated and sent out of the switch as fragments. The packet drop counter is incremented if a temporary shortage of packet memory causes packet fragmentation to fail.

detail extensive

64 octets frames

Number of packets received on the VCP interface (including invalid packets) that were 64 octets in length (excluding framing bits, but including FCS octets).

detail extensive

65–127 octets frames

Number of packets received on the VCP interface (including invalid packets) that were between 65 and 127 octets in length, inclusive (excluding framing bits, but including FCS octets).

detail extensive

128–255 octets frames

Number of packets received on the VCP interface (including invalid packets) that were between 128 and 255 octets in length, inclusive (excluding framing bits, but including FCS octets).

detail extensive

256–511 octets frames

Number of packets received on the VCP interface (including invalid packets) that were between 256 and 511 octets in length, inclusive (excluding framing bits, but including FCS octets).

detail extensive

512–1023 octets frames

Number of packets received on the VCP interface (including invalid packets) that were between 512 and 1023 octets in length, inclusive (excluding framing bits, but including FCS octets).

detail extensive

1024–1518 octets frames

Number of packets received on the VCP interface (including invalid packets) that were between 1024 and 1518 octets in length, inclusive (excluding framing bits, but including FCS octets).

detail extensive

Rate packets per second

Number of packets per second received and transmitted on the VCP interface.

detail extensive

Rate bytes per second

Number of bytes per second received and transmitted on the VCP interface.
