An ASA supports multiple physical interfaces that can be connected into the network or to individual devices. VPC port or VPC member port - is a port that is part of VPC-based port channel. for example, our management vSwitch has two vincs assigned to it (nic1 and nic2). Note: First create the Port-Channel interface and assign the physical interfaces to it using the channel-group 1 mode active command. Helps to minimize frustration. Alternatively, a PC using terminal emulation software can connect directly to a router's console ("con") line over a serial connection. Cisco Small Business 300 1. Password aging settings - see section 16. Verify that EtherChannel is working by issuing the show etherchannel summary command on both switches. member-interface g5 no shut nameif outside security-level 0 ip address 192. What is the purpose and how do I see how many are configured and what ports are apart of these?. + For Layer 2 EtherChannel, physical ports are placed into an EtherChannel group. Use command `show etherchannel summary' to see that etherchannel is working fine. Finally, remember that the perceived bandwidth of a port-channel interface is equal to the sum of its active member links. Please remember to be considerate of other members. # Configure the Port-channel that will be used as the vPC peer-link interface e3/9-10 channel-group 1 mode active interface port-channel1 desc vPC Peer-link switchport switchport mode trunk switchport trunk allow vlan 10,11 no shut # vPC Domains MUST be unique for all vPC pairs configured in an L2 domain vpc domain 1 role priority 1 system. is the port. Cisco's vPC is a virtual port-channel which allows links physically connected to two different switches to appear as a single device to a downstream device as part of a single port-channel. The configuration applied to the port channel will also reflect on physical interfaces that are bundled into that port channel. show interface port-channel x etherchannel HP A Series. Re: Port-Channel Keith Barker - CCIE RS/Security, CISSP Nov 16, 2011 5:46 AM ( in response to Natraj Babaria ) It is interesting that I don't have the option for the "show etherchannel" commands, but the output of the show command for the port-channel interface shows that both interfaces are being used. interface port-channel 1 interface gigabitethernet 1/1 channel-group 1 mode on interface gigabitethernet 1/2 channel-group 1 mode on. Interface fa0/13 and fa0/14 are both in use for this etherchannel. 0(1)SY1 image. This post will expand upon the previous one by bundling two interfaces together on each switch to form an aggregated link for the trunk. Here's one way to verify your configuration. To perform this task, you, as always, rely on the show and debug commands. Note : the command monitor-interface only allows you to monitor interfaces that have been configured with nameif. Cisco Virtual Port Channel (vPC) technology enables multichassis link aggregation (MLAG) in Nexus 5500 data center switches.
