depart from the master chassis' settings to assume the Inconsistent role and Misconfigured-Hello-Interval
status.
To configure the hello interval between the multi-chassis peers, use the virtual-chassis hello-interval
command as shown below:
-> virtual-chassis hello-interval 10
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 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 primary CMM of 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 or EMP-CHAS2). This address can be used for remote access to each switch comprising the
virtual chassis. This address is automatically assigned to the primary CMM of 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.
• It is recommended to have both the EMP-VC IP address and the Chassis EMP IP address configured.
Configuring the Chassis EMP IP Address - Standalone Mode
Use the ip interface command to modify the Chassis EMP IP address as shown below. These commands
would be issued prior to the execution of the convert configuration command.
Chassis1-> ip interface local emp address 10.255.100.1 mask 255.255.255.0
Chassis2-> ip interface local emp address 10.255.100.2 mask 255.255.255.0
Configuring the Chassis EMP IP Address - Virtual Chassis Mode
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
