Configuring the Control VLAN
Under normal circumstances, it is not necessary to change the control VLAN.
However, it is important to note that the VLAN configured as the Control VLAN is reserved specifically
for transferring virtual chassis control information purposes and it can no longer be used for normal data
traffic.
If necessary, use the virtual-chassis configured-control-vlan command to modify the Control VLAN.
For example:
-> virtual-chassis configured-control-vlan 4093
Configuring Virtual Chassis EMP IP Addresses
In order to access the virtual chassis through the EMP IP addresses the port's IP address and network mask
can be configured. There are multiple IP addresses to consider when configuring the EMP IP addresses in
a virtual chassis environment.
• The Virtual Chassis EMP IP address represents the address of the entire virtual chassis (EMP-VC).
This address is automatically assigned to the Master chassis and can be used for remote access to the
entire Virtual Chassis.
• The Chassis EMP IP address is assigned to each switch comprising the virtual chassis (i.e. EMP-
CHAS1, EMP-CHAS2, EMP-CHAS3, etc.). This address can be used for remote access to each switch
comprising the virtual chassis. This address is automatically assigned to the local chassis.
• All the EMP IP addresses and CMM’s IP addresses must be in the same subnet.
• Each of the IP addresses must be unique.
Note: The Virtual Chassis EMP addresses are only supported on OS680E models (non-E models do not
have an EMP port). When configuring VC EMP addresses in a VC with a mix of OS6860E models and
OS6860-non-E models the VC could become unreachable via the EMP port if a non-E model becomes
Master. In a mixed VC environment it's recommended to create a management VLAN for remote manage-
ment purposes.
Configuring the Chassis EMP IP Address
Use the ip interface command to modify the Chassis EMP IP address as shown below. These commands
would be issued after the virtual chassis is operational:
-> ip interface local chassis-id 1 emp address 10.255.100.1 mask 255.255.255.0
-> ip interface local chassis-id 2 emp address 10.255.100.2 mask 255.255.255.0
Configuring the Virtual Chassis EMP IP Address
Use the ip interface command to modify the Virtual Chassis EMP IP address as shown below. These
commands would be issued after the virtual chassis is operational:
-> ip interface master emp address 10.255.100.100 mask 255.255.255.0
