show virtual-chassis vc-port statistics
Syntax
Release Information
Command introduced in Junos OS Release 9.0 for EX Series switches.
The options all-members, brief, detail, extensive, and local were added in Junos OS Release 9.3 for EX Series switches.
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 configuration. |
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 configuration. |
interface-name | — | (Optional) Display traffic statistics for the specified VCP. |
local | — | (Optional) Display traffic statistics for VCPs on the switch or external Routing Engine on which this command is entered. |
member member-id | — | (Optional) Display traffic statistics for VCPs on the specified member of a Virtual Chassis configuration. |

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 | (EX4200, EX4500, and mixed EX4200 and EX4500 Virtual Chassis only) 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 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. | 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:
| 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. | detail, extensive |
