show virtual-chassis protocol adjacency (MX Series Virtual Chassis)

Syntax

show virtual-chassis protocol adjacency<(brief | detail | extensive)><(all-members | local | member member-id)><system-id>

Release Information

Command introduced in Junos OS Release 11.2.

Description

Display the entries (neighbors) in the Virtual Chassis Control Protocol (VCCP) adjacency database for an MX Series Virtual Chassis configuration. You can issue the show virtual-chassis protocol adjacency command from the console of either member router in the Virtual Chassis.

Options

brief | detail | extensive
—

(Optional) Display the specified level of output. Using the brief option is equivalent to issuing the command with no options (the default). The detail option provides more output than the brief option. The extensive option provides complete output and is most useful for customer support personnel.

all-members
—

(Optional) Display the VCCP adjacency database for both member routers in a Virtual Chassis. This is the default behavior if no options are specified.

local
—

(Optional) Display the VCCP adjacency database for the member router on which you are issuing the command.

member member-id
—

(Optional) Display the VCCP adjacency database for the specified member router. Replace member-id with the value 0 or 1.

system-id
—

(Optional) Display the VCCP adjacency database for the device with the specified system ID.

Table 1: show virtual-chassis protocol adjacency Output Fields

Field Name

Field Description

Level of Output

membern

Member ID of the Virtual Chassis member router for which output is displayed.

All levels

Interface

Name of the Virtual Chassis port interface, in the format vcp-slot/pic/port.logical-unit-number.

brief

System

System ID of the device associated with the Virtual Chassis port interface. The System ID is derived from the device’s media access control (MAC) address.

brief

State

State of the adjacency:

  • Up—The adjacency is up.
  • Down—The adjacency is down.

All levels

Hold (secs)

Remaining hold time of the adjacency, in seconds.

brief

system-id

System ID of the device associated with the Virtual Chassis port interface. The System ID is derived from the device’s media access control (MAC) address.

detail, extensive

interface-name

Name of the Virtual Chassis port interface, in the format vcp-slot/pic/port.logical-unit-number.

detail, extensive

Expires in

Number of seconds until the adjacency expires.

Priority

Priority to become the designated intermediate system.

Up/Down transitions

Count of adjacency status changes from Up to Down or from Down to Up.

detail, extensive

Last transition

Time of the last Up/Down transition.

detail, extensive

Transition log

List of recent adjacency transitions, including:

  • When—Date and time at which a VCCP adjacency transition occurred.
  • State—Current state of the VCCP adjacency:
    • Up—Adjacency is up and operational.
    • Down—Adjacency is down and not available.
    • Rejected—Adjacency has been rejected.
  • Event—Type of transition that occurred:
    • Seenself—Possible routing loop has been detected.
    • Interface down—Virtual Chassis port interface has gone down and is no longer available.
    • Error—Adjacency error.
  • Down reason—Reason that a VCCP adjacency is down:
    • 3-Way Handshake Failed—Connection establishment failed.
    • Address Mismatch—Address mismatch caused link failure.
    • Aged Out—Link expired.
    • ISO Area Mismatch—VCCP area mismatch caused link failure.
    • Bad Hello—Unacceptable hello message caused link failure.
    • BFD Session Down—Bidirectional failure detection caused link failure.
    • Interface Disabled—Virtual Chassis port interface is disabled.
    • Interface Down—Virtual Chassis port interface is unavailable.
    • Interface Level Disabled—VCCP level is disabled.
    • Level Changed—VCCP level has changed on the adjacency.
    • Level Mismatch—Levels on adjacency are not compatible.
    • MPLS LSP Down—Label-switched path (LSP) is unavailable.
    • MT Topology Changed—VCCP topology has changed.
    • MT Topology Mismatch—VCCP topology is mismatched.
    • Remote System ID Changed—Adjacency peer system ID changed.
    • Protocol Shutdown—VCCP is disabled.
    • CLI Command—Adjacency brought down by user.
    • Unknown—Unknown.
