Issue

ISL (Inter-switch link) interface is suspended and down even after correctly following all the steps and rebooting twice to install the new RCF version 1.11 or 1.12a.
Seeing this error during the first switch reload and RCF installation is expected:

sw1(config-if)# channel-group 1 mode active TCAM region is not configured. Please configure TCAM region and retry the command

Seeing this error after the second switch reload and RCF installation is NOT expected and the steps in the solution section will need to be followed:

sw1(config)# interface eth1/31 sw1(config-if)# channel-group 1 mode active command failed: port not compatible:[Port priority-flow-control] ** You can use force option to override the port's parameters ** (e.g. "channel-group X force") ** Use "show port-channel compatibility-parameters" to get more information on failure

To verify this is the issue experienced and certain configuration lines on the ISL ports were not able to be applied follow the example below. In the example sw1 is experiencing this problem and sw2 is successfully updated:

Review the running configuration on the ISL interfaces (in this instance Eth1/31 and Eth1/32):

`show running-config eth1/31 show running-config eth1/32`	`show running-config eth1/31 show running-config eth1/32`
Sw1 - Problem	Sw2 - Working
`interface Ethernet1/31 description Intra-Cluster Switch ISL Port 1/31 (port channel) switchport mode trunk switchport trunk allowed vlan 1 priority-flow-control mode on mtu 9216`	`interface Ethernet1/31 description Intra-Cluster Switch ISL Port 1/31 (port channel) switchport mode trunk switchport trunk allowed vlan 1 priority-flow-control mode on mtu 9216 channel-group 1 mode active`
`interface Ethernet1/32 description Intra-Cluster Switch ISL Port 1/32 (port channel) switchport mode trunk switchport trunk allowed vlan 1 priority-flow-control mode on mtu 9216`	`interface Ethernet1/32 description Intra-Cluster Switch ISL Port 1/32 (port channel) switchport mode trunk switchport trunk allowed vlan 1 priority-flow-control mode on mtu 9216 channel-group 1 mode active`

2. Review the interface status:

3. It is noticed that there are no configured member ports for this port channel:

4. Comparison with the successfully updated switch sw2 shows that there are no LACP frames received from sw1:
