I am about to configure 4 Gig ports for EtherChannel. I've been reading about EtherChannel and it seems easy enough to configure. I have a host (server)which I am going to connect to these 4 - gig ports. This is new for me and would like some feedback for those that have used EtherChannel on their layer 2 switches. The gig ports will be an access port with VLAN XX.
View 6 RepliesI have 2 x WS-X4548-GB-RJ45 Catalyst 4500 Enhanced 48-Port 10/100/1000 Base-T (RJ-45) line cards in a 4500 chassis with 2 x WS-C4507R-E E-Series Super visor engines. We would like to create a layer 3 ether channel from a access layer switch terminating on our 4500 chassis. Can we configure the ether channel from the access layer switch such that one port on the ether channel is on one line card and the other one is on the other line card?

I am trying to implement an etherchannel on a cisco 2901 (IOS 15.1). i have already created the port-channel but i cannot assign the gig interface to the channel group.
View 1 Replies View RelatedI have a problem with an etherchannel between a cisco 2950 and a couple of catalyst 4506. The cisco 2950 is connect via an etherchannel to the catalyst 4506A. The channel consist of two port on both side and is in trunk mode, encapsulation dot1q.Now i have the necessity to connect the 2950 to the other catalyst, 4506B. So, i copy the same configuration on the 4506B, but when I unplug the two rj45 cables from the catalyst 4506A to plug them in the 4506B the etherchannel doesn't go up in any way.

View 1 Replies View RelatedIs it possible to have ether-channel across 2 switches? As an example, having a server with 2 ports connect, 1 port to Switch-A and the other to Switch-B and then use those two links on the sepatate switches but to the same server to form an Etherchannel.
The Switch-A and Switch-B are 3560 series
We have two 6k5 configured as vss and it is working fine. For each floor we have a 3750 stack. In each 3750 stack we have 4 switches. From the first 3750 we have a fiber link to the first 6k5 and from the fourth switch we have another fiber link to the other 6k5 switch, for each floor/3750 stack, both configured as etherchannel. We installled each 3750 stack/floor in different maintenance windows; in all these installations we have problems configuring the etherchannel. After we configure the etherchannel on 3750 stack and in the vss, the etherchannel does not go up/up. We see the etherchannel up/down; after a lot off work, try and error, configuring shut/ no shut, adding and excluding links from the etherchannel; in any aleatory moment the etherchannel goes up/up and works fine. Is there any bug related with these IOS versions, or is there any right procedure to configure etherchannel from vss to 3750 stack?

I am trying to review the port-channel configuration on a 6500 series. I am issuing the "show etherchannel summary" command and the out put shows the Group, Port-Channel, and Ports. It does not show me the protocol that is in use such as PAgP or LACP. Does this have to do with the Etherchannel in the "On" mode rather than "active", or "Auto"?
View 2 Replies View RelatedWe have a problem with the throughput over etherchannel in LACP with 2 or 4 ports. It is iSCSI traffic (vmware esxi 4.1 U3) is going from 2 separate NICs (ports) to the etherchannel (with 2 or 4 ports) that has a SAN connected (Nexenta).
The SAN is configured in passive LACP and the switch is in active LACP. Actually it does not matter if we do LACP or just MODE ON, still same result: ~1GBit/s throughtput in either direction. Like already mentioned, 2 or 4 ports in the etherchannel make no difference, or the configuration of the etherchannel.
I will post some config data below, but here is the question: Why can't we see traffic beyond 1GBit/s? Source and destination are capable of doing much more than that (vmware esxi RAID 5 of 1TB SATA; SAN 16 x 1TB NL-SAS). If we look with CNA, we can see that the traffic is balanced equally over the etherchannel ports. With or without QOS or flowcontrol, no difference. This whole traffic happenes on this switch.

When you aggregate multiple fiber GBICs together on the 3508G, do you configure it as an etherchannel, or as fibre-channel? I've looked around online for hours, but can't find it mentioned anywhere.

View 8 Replies View RelatedIs it possible to to build a Layer 3 ether channel from two separate physical switches (layer3) that are trunked together?I know you can easily do this on a single switch and on stacked switches which I've done but in this case the customer have purchased two 3560X's which are not stackable yet want redundancy. The purpose of the etherchannel is to connect both switches to a private circuit provided by the hosted partner then route to the same setup in the DR location to different subnets.

View 3 Replies View RelatedI was configuring link aggregation between a Cisco3750 and Cisco SG200 and the switched network went down just a few minutes after the port channel came on.I rebooted the SG200 and all hosts came back up for a minute before I lost them again. The etherchannel was between two trunking ports. I never set link aggregation on the SG200, could that be the reason? All machines are connected to the SG200. The 3750 is only being used as a layer 3 device for inter vlan traffic.

View 1 Replies View RelatedWe have a new building where we added 3 network closets with 3750x stacks.We have 2 fiber gig ports connected to 2 microwave units and etherchanneled the to ports
We have the same setup at the corporate office except the connection is 2 fiber gig ports on a 6509. The 6509 is doing the routing
Now the problem is that we lost the connection to the management interface on only one of the three closets after a few days running. But some workstations at the corp office could reach it... others could not. The workstation were on the same VLAN. We solved the problem for a few days by shutting on of the fiber ports on the etherchannel. But is started happening again... now with PCs being installed at the new location.
The PC that was not working on the 3750x side could ping across to the 6509 but no further then that. It seems like an arp issue not routing because some devices are reachable and fully operational throughout the network.
