IP Management for Out-of-Band Management

Initial Configuration Guidelines

The following steps must be done from the console port.

When configuring Skylight Flex 100, use Configure Static IP and Default Gateway or DHCP Client Configuration Procedure.

Configure Static IP and Default Gateway

To configure the IP address

1. After software installation, use the following command on the Skylight Flex 100 console:

Your Product# configure terminal
Your Product (config)# interface cpu0 
Your Product (config)# shutdown
Your Product (config)# ip address <flex-ip-address> <netmask: 255.255....>
Your Product (config)# no shutdown

• The following command adds a default static route to the out-of-band (OOB) management interface.

Your Product# configure terminal
Your Product(config)# ip route 0.0.0.0 0.0.0.0 cpu0
Your Product(config)#end
Your Product#

• The following command adds a default static route to the gateway address.

Your Product# configure terminal
Your Product(config)# ip route 0.0.0.0 0.0.0.0 <ip-default-gateway>
Your Product(config)#end
Your Product#

• If needed, the no form of the following command deletes a static route.

Your Product# configure terminal
Your Product(config)# no ip route 0.0.0.0 0.0.0.0 cpu0
Your Product(config)#end
Your Product#
Your Product# configure terminal
Your Product(config)# no ip route 0.0.0.0 0.0.0.0 <ip-default-gateway>
Your Product(config)#end
Your Product#

The following command verifies the routing table.

Your Product# show ip route

Codes: C - connected, S - static, R - rip, B - bgp, O - ospf, I - isis, E - ECMP
IA - OSPF inter area, N1 - OSPF NSSA external type 1,
N2 - OSPF NSSA external type 2, E1 - OSPF external type 1,
E2 - OSPF external type 2 L1 - ISIS Level1, L2 - ISIS Level2, ia - ISIS Inter Area

Vrf Name: default
---------
0.0.0.0/0 [0/1] via 16.0.0.254
C 16.0.0.0/8 is directly connected, cpu0

DHCP Client Configuration Procedure

The following command configures the OOB management interface to dynamically acquire IP address from the DHCP server.

Your Product# configure terminal
Your Product(config)# interface cpu0
Your Product(config-if)# ip address dhcp
Your Product(config-if)# end
Your Product#

• The following command verifies the OOB management interface dynamic address allocation.

Your Product# show ip interface

cpu0 is up, line protocol is up
Internet Address is 0.0.0.0/0
Broadcast Address 255.255.255.255
IP address allocation method is dynamic
IP address allocation protocol is dhcp
Your Product# show ip interface

cpu0 is up, line protocol is up
Internet Address is
Broadcast Address 16.255.255.255
IP address allocation method is dynamic
IP address allocation protocol is dhcp

• The following command verifies the routing table.

Your Product# show ip route

E2 - OSPF external type 2 L1 - ISIS Level1, L2 - ISIS Level2, ia - ISIS Inter Area
Vrf Name: default
---------
0.0.0.0/0 [0/1] via 16.0.0.254
C 16.0.0.0/8 is directly connected, cpu0

• The following command enables an OOB interface.

Your Product# configure terminal
Your Product(config)# interface cpu0
Your Product(config-if)# no shutdown
Your Product(config-if)# end
Your Product#

• MIB Config Save and Restore

• The following command writes the running-config to a startup-configuration file:

Your Product# write startup-config

• The following command restarts the switch:

Your Product# reload

• The no form of the command resets the IP address of the interface to its default value:

Your Product# configure terminal 
Your Product(config)# interface cpu0
Your Product(config-if)# no ip address
Your Product(config-if)# end
Your Product#

• The following command sets the static IP address to the OOB interface:

Your Product# configure terminal
Your Product(config)# interface cpu0
Your Product(config-if)# ip address <flex-ip-address>
Your Product(config-if)# end

Bridge Mode Configuration Procedure

This step is necessary for changing the bridge mode from customer bridge to Provider Edge Bridge.

▶ To configure Bridge Mode

1. Shutdown the Spanning Tree on Skylight Flex 100.

Your Product# configure terminal
Your Product(config)# shutdown spanning-tree
Your Product(config)#end
Your Product#

2. Disable the ECFM module on Skylight Flex 100.

Your Product# configure terminal
Your Product(config)#no ethernet cfm start
Your Product(config)#end
Your Product#

3. Set the bridge mode type to Skylight Flex 100.

Your Product# configure terminal
Your Product(config)# bridge-mode provider-edge
Your Product(config)#end
Your Product#

4. Execute the below command to save the running configurations to start-up configuration. This step allows the user to keep the OOB Management interface settings while changing the Bridge Mode.

Your Product# configure terminal
Your Product(config)# write startup-config
Your Product(config)#end
Your Product#

5. Reload the Skylight Flex 100 using the below CLI command.

Your Product# configure terminal
Your Product(config)# reload
Your Product(config)#end
