a Customer ask me to configure a etherchannel between two Switches C3500 XL Version IOS 12.0 follow the first configuration what I done and the output error show me by switch:
I have created 5 new 2 Gig port channels on a 6513 WS-X6516A-GBIC blade connecting to 5 4510R+E switches. 3 of the 5 Port-channels show up/up. 2 show down/down. However, for the 2 showing down, a duplicate Po interface was created with an "A" appended to the name that shows up/up. E.g:
Port-channel26 unassigned YES unset down down Port-channel26A unassigned YES unset up up
Each of the 4510s has a second 2Gig PO to another 6513 with an identical config and all of those come up fine.
how to configure this. I did it in the past but kind of forgot how I did it.I have a stacked 3750 (two physical switches) connecting to a 2960.
I am creating trunk ports with limited access to VLAN 300, 600, and 700.
There is two interfaces connected from the 3750's(one on each physical stack member) to the 2960.I have the physical interfaces configured exactly the same.
Should I keep the configuration on the physical ports and not configure the Port-Channel Interfaces? Do I need to configure port-channel load balancing? Is the channel-group mode sufficient? Goal is to basically create 2 links to the 2960 to double the bandwidth and provide redundancy.
Here is an example of what each switch logs when a server drops offline. Sample logs taken between 5:32am and 5:35am on Feb 20. This particular one was having problems all weekend. Switch #1 encountered over 2000 interface resets. The corresponding VPC port on Switch #2 only had 13 resets.

We have added GLC-SX-LH module to E1/1 and E1/10 and speed is set to 1000 (1Gig) Now other side of E1/9 and E1/10 are not connected. Port-channel status is down
Po105 1 eth trunk down No operational members 1000(D) lacp
show interface port-channel 105 shows different bandwidth (100) MTU 1500 bytes, BW 100000 Kbit, DLY 10 usec,question is under interface port-channel105 speed 1000 command inserted automatically.Now if we connect otherisde of interface, during port-channel comes up.what will be the port-channel interface bandwidth ? will it change to 2Gig(2000). Why speed 1000 command inserted automatically on port-channel.Since it is migration, we want to be more specific on the port-channel configuration?
I have two 3750Xs for stack, and i want connect a 2960 switch on this stack with port-channel.I connect 2960 G0/1 to 3750X G1/0/24, and 2960 G0/2 to 3750X G2/0/24. [code] i try to config spanning-tree etherchannel guard misconfig, but no use finally, i have to use "no errdisable detect cause all"..i check the cisco.com, and find a information: for this case, channel-group can use mode desirble.but when i try to change the channel-group in 3750X stack, it shows me that: "with pagp enable, desirble mode must config in the same switch".i try to use mode desirble mode in G1/0/23 and G1/0/24 in 3750X stack, it still can not work.i want to know how to solve this problem? not only do "no errdisable detect cause all".
There is a cisco ws-c6509,recently it appear error log “%FABRIC-SP-6-TIMEOUT_ERR: Fabric in slot 5 reported timeout error for channel 11 (Module 3, fabric connection 1)”. When I reload the device,the error log disappear.But a few days later,it appears again.I try to replace the slot 3 (WS-X6704-10GE),the error log continues.The IOS version is 's72033_rp-ADVIPSERVICESK9_WAN-M), Version 12.2(18)SXF8"
I have 3750 core/distribution switches with routing enabled in two offices connected with copper link and L3 port channel interfaces. NewOffice#2 has moved about 5 miles farther away from office#1 and I have to deploy new core/distribution switch connect it to old core#2 via F.O and move all access switches with it. Old core will stay in old #2 offices as a bridge between office#1 and new office#2 Office#1core<->copper (Ethernet) <->oldoffice#2core<->f.o. <->new office#2core How I should configure port channels ports on oldoffice#2 core to act as bridge between office#1 core/dist and newoffice#2 core/dist without changing anything else (ip, etc) on whole network
I have 2 Cisco 6509 switches linked together via single Fibre as a trunk.I want to change this to a port channel where I will add another 3 fibre ports to the port channel but what order do I do this to minimise any disruption.
1-Configure PortChannel and add the 3 new ports, this will bring up the Port Channel but what effect will this have on traffic currently going over the single Trunk link? Will spanning tree go mad, how will switches react?
2-Convert existing Trunk link to Portchannel then add in new ports to PortChannel, I guess in doing this there will be a small hit on traffic as it changes to a port channel.
We have 2 6513's that are linked via 2 10 gig interfaces, using an LACP channel.I received an alert this aft stating that the far 6513 was unreachable and the port channel int PO3 had gone down, the 2 10 gig interfaces had also gone down on either side. 5 mins later PO3 had resestablished itself and has been fine since.

We are running nexus 5018 in our DC.What is the difference betwen "channel-group 214 mode active" and " channel-group 216" Any difference?.. because i have problem with this config we are going build a server config?
We have problem with porth channel down.

I am building a new network and intended on using the min-link feature on my port-channels between a 3750-X series switch and Nexus 4k.
However reading further into this it seems this feature is only supported on higher end models. I cannot find any reference to the min-links feature in the 3750-X configuration guide. Is this an available feature?
The 3750-X model is WS-C3750X-24T-L running IOS 12.2(55)SE3 IP Services
My thoughts is that the is only an LACP supported feature so I may not see the command until I have entered an LACP specific command on the port-channel but unfortunately I do not have a 3750X to verify this on at present.
We have one 3825 router used as voice gateway. For redudancy, we want to connect it to two different switches which has STP and HSRP running. Can I create a port-channel with two Giga interfaces in 3825 and connect to two different switches? Should I configure port channel in switch with only one port in each port-channel? I know server can be connected to different switches with NIC teaming. I just want to mimic that kind of setup. I did one time for port-channel in 3825, but it was connected to a stacked 3750X. So it's different case now.
I am trying to configure port-channel from one switch to two switchs, and only one interface of each switches make part of the port channel.Cisco IOS Software, ME380x Software (ME380x-UNIVERSALK9-M), Version 12.2(52)EY4, RELEASE SOFTWARE (fc1) [code]
I have a pair of 6500's setup with VSS and there is currently only one link between then. However one end of the link is on Po10 and the other end is on Po25. If I move the Po25 over to Po10, will things break? It seems to be working fine now. I'm about to add a second link and I'm concerned about the current configuration. It makes more sense to me to have both ends of the same link on the same port-channel ID. I've seen documentation which states otherwise however.

I am using 3560.IP rouitng is being turned off on this.Curious to know if I will create etherchannel or port channel.I think etherchannel.Correct me if I am wrong.On connecting switches I have vlan10,20,30 to be allowed.I am sure I need to allow these all vlan in 10,20,30 which are on the trunk port on each side switch.Post that will add channel-port lacp and make it in active mode.Is that correct.This way traffic will be load-balanced/aggregated on minimum 2 ports who are the part of this.
Here's what I'm trying to do. We are having new storage servers installed that will be using NFS. I'm being told that they need to have their connections port channeled. Right now, the servers have connections to 2 different 3750s for HA. Is it possible to configure a port channel between these 2 connections?
I have an inquiry about a configuration I deploy in a C2960 switch. I have configured a ether channel with 8 ports, the load balanced method is source mac address. The bundling protocol is LACP.
I have found the ether channel is not balanced as I expect. One of the eight interfaces is congested.
We have a switch that, when configuring auto qos on and edge port facing video equipment, the upstream port channel drops. I was wondering if no auto qos would have to be configured on the member ports of the port channel prior to enabling auto qos on any other ports.
I have a Cisco 6500 series switch with VS-C6509E-S720-10G ,I have two redundant supervisors between two chassis on the LAN with no add-on line cards ?
I need to know if I can use the redundant supervisor 10 Gb uplinks to form a layer-2 Port channel between the two 6500 switches as i do not want to use want to keep the port idle additionally I need more bandwidth between the two switches for my server farm?
I have 2 cisco 6500 in a VSS configuration , All of my Lan access switches are Stack switches and every Stack is connected to the VSS in a Port-channel so basically this is a loop free environment with no blocked ports .As a best practice I left STP in the Background (mstp)which enhanced cisco features to STP should I configure on the Aggregator (6500-VSS) and on the Access switches ?
Because of my topology I dont see the need in configuring most features like Uplink Fast and Backbone Fast but I have configured Loop Guard in addition to UDLD on the 6500 Aggregation Switches (on the port-channels).On the access ports I have configured portfast , bpduguard and guard root (seems a little pointless to configure the two...)
1.should I Leave UDLD on and get rid of LoopGuard and configure Guard root instead ? since LoopGuard cannot be configured with Guard Root.
2.should I configure GuardRoot on access ports if I already have BpduGuard on them ?
3.Is there anything I need to configure on the physicall interface or is everything configured on the port-channel since STP reguards port- channel as a single interface ?
I am trying to create a port channel between HP servers (4 nic) and two nexus 2k. The server side its a single team with 803.2ad fault taulerence and on the nexus side it have created two port channel (port channel 1 for nexus 2k1 and port channel 2 for nexus 2k2) and made them ACTIVE (channel group mode active)
But when i add a another server on different ports and port channel them the same way as the above server on nexus 2k1 and nexus 2k2, the first server stops pinging. so i have to sht down the first port channel and reopen them - then it works, however it says NO NETWORK ACCESS on the servers (running windows 2008). the only way is to reboot the server i cant be doing this on a production network.
Is it possible to use a 10GE interface on a sup720 and an interface from a 671610GE line card and create a port channel. I haven't found specific documentation on CCO stating you can. I have found the QOS queuing is differnet between the sup and line card.
I need adding a vlan to the trunks bundled in port channel. I know how to add v lans to a port channel with Cisco IOS but with CAT OS.
I have 2 ports bundled to form ether channel in switch which is running CAT OS. There are already few v lans allowed in the trunk of each interface. now I need to add one more v lan.
For Example:- v lan 135 needs to be added in addition to the existing v lans.
clear trunk1/2 1-112,115,117-134,136-4094 set trunk 1/2 on dot1q 113-114,116,135
and similarly on the 2nd interface
so if I add vlan135 to the trunk one after another will it cause any service disruption?
I am having hard time in understanding the hardware port channel resource concept in Nexus 5Ks. Which scenario is considered as a hardware port channel and which is not. According to Cisco documentation, 5548UP switch with layer 3 daughter card only supports 8 hardware port channels, does this mean we can connect only 8 dual homed Fex to those 5Ks.Will a dual homed fex consumes a hardware port channel?
I have two Core 6509E SUP2T configued as VSS and has two 48 ports fiber blades. I have two 3750s, I have two gig on each 3750 port-channle to po1 and connected to both the core, one link to each core.Now, I was asked ot add two more links on each 3750 switch to make it a total of 4 gigs on each 3750s (all 4 gig ports/uplinks will be in used an dtwo links to core one an dtwo links to core 2).when i added two additional links on 3750s and bundled them to po1, I created another port channel on core and bundeled the additional two gigs on each core to accomodate for the two additional links (ports on core switches are not consequtives).
adding these two additional ports makes the 3750 switches flap between managemnet vlan and po1.now, i am not sure if I must have added the two additional links on the core to teh current port-channel or core!? I have created another port-channel on core to accomodate for this currently!?
