vcp-1 Dedicated 2 Up 32000 2 vcp-1
1/0 Auto-Configured —1 Up 1000 1 vcp-255/1/0
Meaning
The dedicated VCPs are displayed as
vcp-0
and
vcp-1
. The interface on the switch that
has been set as an uplink VCP is displayed as
1/0
. The member interface names of uplink
VCPs are of the form
vcp-255/pic/port
—for example,
vcp-255/1/0
. In that name,
vcp-255
indicates that the interface is an uplink VCP,
1
is the uplink PIC number, and
0
is the uplink
port number. The
fpc
number is the same as the member ID. The
Trunk ID
is a positive
number ID assigned to the LAG formed by the Virtual Chassis. If no LAG is formed, the
value is
–1
.
Troubleshooting
To troubleshoot a Virtual Chassis configuration that is interconnected across wiring
closets, perform these tasks:
Troubleshooting Nonoperational VCPs
Problem
A uplink VCP shows a status of
down
.
Solution
Check the cable to make sure that it is properly and securely connected to the ports.
•
•
If the VCP is an uplink module port, make sure that it has been explicitly set as an uplink
VCP.
•
If the VCP is an uplink module port, make sure that you have specified the options
(
pic-slot
,
port
, and
member
) correctly.

EX Series switches allow you to combine multiple Ethernet links into one logical interface
for higher bandwidth and redundancy. The ports that are combined in this manner are
referred to as a link aggregation group (LAG) or bundle. The number of Ethernet links
you can combine into a LAG depends on your EX Series switch model. See “Understanding
Aggregated Ethernet Interfaces and LACP” on page 1099 for more information.
