适用场景

Cisco Nexus 3232C集群交换机
Cisco Nexus C3132Q-V集群交换机
Cisco Nexus C9334C-拧开集群交换机
RCF (参考配置文件)版本1.11、1.12或 1.12a

警告

此知识库文章不适用于MetroCluster IP配置。

问题描述

即使正确执行了所有步骤并重新启动两次以安装新的 RCF1.11或1.12a、ISL (交换机间链路)接口也会暂停和关闭。
应在首次重新加载交换机和安装RCC期间看到此错误：

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

在第二个交换机重新加载并安装RCC后、您不会看到此错误、需要遵循解决方案部分中的步骤：

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

要验证这是否为问题描述体验、以及无法应用ISL端口上的某些配置行、请按照以下示例进行操作。在示例中、 sw1 遇到此问题、并且 SW2 已成功更新：

查看ISL接口上的运行配置(在此示例中为Eth1/31和Eth1/32)：

`show running-config eth1/31 show running-config eth1/32`	`show running-config eth1/31 show running-config eth1/32`
SW1 -问题	SW2 -工作
`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.查看接口状态：

sw1# show interface brief

------------------------------------------------------------------------------------------ Port-channel VLAN Type Mode Status Reason Speed Protocol Interface ------------------------------------------------------------------------------------------ Po1 1 eth trunk down No operational members auto(I) lacp Po999 1 eth access down Administratively down auto(I) none

3. 请注意、没有为此端口通道配置成员端口：

sw1# show port-channel  summary
 Flags:  D - Down     P - Up in port-channel (members)
      I - Individual  H - Hot-standby (LACP only)
      s - Suspended   r - Module-removed
      b - BFD Session Wait
      S - Switched   R - Routed
      U - Up (port-channel)
      p - Up in delay-lacp mode (member)
      M - Not in use. Min-links not met

 999   Po999(SD)   Eth     NONE      --

4.与已成功更新的交换机SW2进行比较后、发现未从sw1收到LACP帧：

sw2# show interface brief

sw2# show port-channel summary
