What is a channel group Cisco?
A port channel bundles individual interfaces into a group to provide increased bandwidth and redundancy. For example, if you configure Spanning Tree Protocol (STP) parameters on the port channel, Cisco NX-OS applies those parameters to each interface in the port channel.
What is the difference between port channel and channel group?
Channel Groups and Port Channels A port channel is also referred to as a Link Aggregation Group (LAG). Port channels combine the bandwidth of multiple Ethernet ports into a single logical link. A channel group is a collection of Ethernet interfaces on a single switch.
How do I find my port channel group?
To verify that the port channel configuration is present in the profile used by the physical ports, enter the show port-channel name name command and check for the channel-group auto setting.
What is Po1 Cisco switch?
PO1 is the etherchannel interface – Port channel interface. You can use Po1 interface as Layer 2 or Layer 3 interface incase of L3 you can assign IP to Po1 interface.
How do I set up a group channel?
Assign the port to a channel group, which is an integer between 1 and 6. You also configure PAgP or LACP at this time by specifying a mode, as listed in the below table….EtherChannel Configuration.
| Mode | Protocol | Description |
|---|---|---|
| Passive | LACP | Sets the interface to respond to LACP data if it receives negotiation requests from other systems. |
What is a port channel group?
A port channel is a communication link between two switches supported by matching channel group interfaces on each switch. A port channel is also referred to as a Link Aggregation Group (LAG). Port channels combine the bandwidth of multiple Ethernet ports into a single logical link.
How does a port channel work in Cisco?
A port channel bundles physical links into a channel group to create a single logical link that provides the aggregate bandwidth of up to eight physical links. If a member port within a port channel fails, the traffic previously carried over the failed link switches to the remaining member ports within the port channel.
What does the port channel group do in LACP?
• Passive—Places a port into a passive negotiating state, in which the port responds to LACP packets it receives but does not initiate LACP negotiation. In this mode, the port channel group attaches the interface to the bundle.
What do you need to know about link aggregation Control Protocol?
For more flexibility, you can use the Link Aggregation Control Protocol (LACP), which is defined in IEEE 802.3ad. When you use LACP, the link passes protocol packets. You cannot configure LACP on shared interfaces.
What are the three modes of Port channeling?
When it comes to port-channeling there are three modes, “Active”, “Passive” and “on”. “on” is just being on, no negotiation. Hope that answers your question. 05-06-2012 01:41 PM 05-06-2012 01:41 PM Unfortunately, the above poster had some wrong information. While “desirable” is a DTP negotiation mode, it is also a ether channel mode.
