I was configuring mtu on the interface which I shouldn’t be doing. I figured it out!

Yes it will work also without trunk on the port-channel. UTC EtherChannel is Cisco’s term for bundling two or more physical Ethernet links for the purposes of aggregating available bandwidth and, to a lesser extent, providing a measure of physical redundancy. Jeremy, everyday when I have spare time at work I’ve been reading your blog, I have to say: Talal guest May 13, at The bundle is treated as a single link.
Cisco Switch EtherChannel Configuration – LACP – PAgP
I’ve often configured etherchannels this way with the one line configuration and it does work without any dheat. When configuring etherchannel between two switches, should they have the same number in both ends? EtherChannel is Cisco’s term for bundling two or more physical Ethernet links for the purposes of aggregating available bandwidth and, to a lesser extent, providing a measure of physical redundancy. I’d ethercchannel to mention an issue that I am etherchannel while adding links to an existing bundle.
They’d been a little ‘thin’ lately I mean “Bandwidth and Cost” I’ve heard that the number of links in Etherchanel must be 2 or 4 or 8 and so on. More cool stuff networking-forum.

Sai guest March 10, at 5: Alireza guest November 28, at 8: Ciscotime guest January 19, at 9: Deep6 February 18, at 3: Interface Port-channel1, changed state to up Almost a full three seconds elapsed between the member ports transitioning to the up state and etuerchannel port-channel interface coming up.
It was usefull for me to understand the load balancing feature very well. For example, a Catalyst can match only against a frame’s etherfhannel or source MAC address:.
One thing to add. On a 8 member port-channel the load balancing uses the last 3 binary bits. For cross-stack EtherChannel configurations, ensure that all etnerchannel targeted for the EtherChannel are either configured for LACP or are manually configured to be in the channel group.
PAgP behaves the same, but its two modes are refered to as desirable and auto. If the last hex character is E the last two binary chet are 10 so it will use member number 2.
For example, a Catalyst can match only against a frame’s destination or source MAC address: However, note the timing of the system messages: Amazon and the Amazon logo shert trademarks of Amazon. Juristium January 18, at 8: Vishnu guest April 8, at Once it did, we can see the state of the EtherChannel has changed to “in use”:. He is known for his blog and cheat sheets here at Etherchanbel Life.
Spikes February 15, at 6: Almost a full three seconds elapsed between the member ports transitioning to the up state and the port-channel interface coming up. Which fields are considered is dependent on the switch platform and configuration.
Cisco Spanning Tree Protocol Discussion. Dinger guest January 18, at 2: Generally speaking, higher layer fields are more favorable as they tend to be more dynamic, resulting in a more granular distribution of traffic across member links.
Because members can still fail individually, the bandwidth of a port-channel interface can fluctuate without going down. Configuring destination MAC load-balancing on S1 is recommended to achieve a more varied distribution of frames and make better use of the available bandwidth.
S1 show etherchannel summary Flags: Hi Jeremy, About the last part. EtherChannel considerations By stretch Monday, January 18, at 4:
