Configuring switches from factory default configuration

  1. Insert stacking module into Module Bay 1.

  2. Insert switches into A1 and A2.

  3. Connect switch cables:

    1. Connect A1-xg1 with A2-xg2.
    2. Connect A1-xg2 with A2-xg1.
  4. Wait a few minutes and then use one of the following methods to determine which switch is the M6220 stack master switch:

    1. Identify the master switch by the blue illuminated LED just below the serial console connector.
    2. SSH to CMC and run the following command.

    3. Check the Role column in the I/O Module Status table in CMC Web UI management.

  5. Connect to the master switch. From a CMC SSH session, use the connect switch-1 or connect switch-a1 command.
    Note:

    To connect to the member switch, use the connect switch-2 or connect switch-a2 command from a CMC SSH session. If you are connected to the member switch, the console will print the following message.

    Unit 2 - CLI unavailable - please connect to 
master on Unit 1
    1. Configure spanning-tree (default value is 32768; priority is 57344).
    2. Add VLAN information (depending on customer environment).
      console#config
console(config)#vlan 4000
console(config-vlan4000)#name example
console(config-vlan4000)#exit
console(config)#
    3. Run the following command for interfaces 1-16 on both switches.
      console#config
console(config)#spanning-tree priority 57344
console(config)#interface range gigabitethernet 1/0/1-16
console(config-if)#spanning-tree guard root
console(config-if)#switchport mode trunk
console(config-if)#switchport trunk allowed vlan all
console(config-if)#exit
console(config)#interface range gigabitethernet 2/0/1-16
console(config-if)#spanning-tree guard root
console(config-if)#switchport mode trunk
console(config-if)#switchport trunk allowed vlan all
console(config-if)#exit
console(config)#exit
console#write
This operation may take a few minutes.
Management interfaces will not be available during this
time.

    4. Shut down reserved external interfaces (17-20)
      console#config
console(config)#interface range gigabitethernet 1/0/17-20
console(config-if)#shutdown
console(config-if)#exit
console(config)#interface range gigabitethernet 2/0/17-20
console(config-if)#shutdown
console(config-if)#exit
console(config)#exit
console#write
This operation may take a few minutes.
Management interfaces will not be available during this
time.

    5. Create a port channel. In the example below, the uplink ports are 10 gigabit Ethernet ports 1/2/1 and 2/2/1. They use dynamic LAG (static command is channel-group 1 mode on), which is consistent with the other side ports of the uplink switch.
      console#config
console(config)#interface tengigabitethernet 1/2/1
console(config-if-Te1/2/1)#channel-group 1 mode active
console(config-if-Te1/2/1)#exit
console(config)#interface tengigabitethernet 2/2/1
console(config-if-Te2/2/1)#channel-group 1 mode active
console(config-if-Te2/2/1)#exit
console(config)#interface port-channel 1
console(config-if-Po1)#spanning-tree disable
console(config-if-Po1)#switchport mode trunk
console(config-if-Po1)#switchport trunk allowed vlan all
console(config-if-Po1)#exit
console(config)#exit
console#write
This operation may take a few minutes.
Management interfaces will not be available during this
time.
