show virtual-chassis vc-port statistics

Syntax

Description

Display the traffic statistics collected on Virtual Chassis ports (VCPs).

Options

none

Display traffic statistics for VCPs of all members of a Virtual Chassis or VCF.

brief | detail | extensive

(Optional) Display the specified level of output. Using the brief option is equivalent to entering the command with no options (the default). The detail and extensive options provide identical displays.

all-members

(Optional) Display traffic statistics for VCPs of all members of a Virtual Chassis or VCF

interface-name

(Optional) Display traffic statistics for the specified VCP.

local

(Optional) Display traffic statistics for VCPs on the switch or external Routing Engine where you enter this command.

member member-id

(Optional) Display traffic statistics for VCPs on the specified member of a Virtual Chassis or VCF.

Output Fields

Table 1 lists the output fields for the show virtual-chassis vc-port statistics command. Output fields are listed in the approximate order in which they appear.

Table 1: show virtual-chassis vc-port statistics Output Fields

Field Name

Field Description

Level of Output

fpcnumber

(All Virtual Chassis except EX8200 Virtual Chassis. VCF) ID of the Virtual Chassis member. The FPC number is the same as the member ID.

All levels

member number

(EX8200 Virtual Chassis only) Member ID of the Virtual Chassis member.

All levels

Interface

VCP name.

brief

Input Octets/Packets

Number of octets and packets received on the VCP.

brief, member, none

Output Octets/Packets

Number of octets and packets transmitted on the VCP.

brief, member, none

master: number

Member ID of the primary Routing Engine.

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.

detail, extensive

Total packets

Total number of packets received and transmitted on the VCP.

detail, extensive

Unicast packets

Number of unicast packets received and transmitted on the VCP.

detail, extensive

Broadcast packets

Number of broadcast packets received and transmitted on the VCP.

detail, extensive

Multicast packets

Number of multicast packets received and transmitted on the VCP.

detail, extensive

MAC control frames

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

detail, extensive

CRC alignment errors

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

detail, extensive

Packet drop events

Number of outbound packets received on the VCP 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 (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 (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 (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 (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 (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 (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.

detail, extensive

Rate bytes per second

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