Cisco Switching/Routing :: 6513 / Port-channel Down But Duplicate Interface Created With (A) Up?
Nov 12, 2012I 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.
Cisco Switching/Routing :: Configure Port-Channel Or Physical Interface On 3750
Jan 12, 2012how 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.
3750 Config:
interface Port-channel2
!
interface FastEthernet1/0/46
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1, 300,600,700
switchport mode trunk
speed 100
[code]....
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.

Cisco Firewall :: Port-channel On ASA 5520
Jun 11, 2013So everything I've read on Cisco's documentation here: URL says that I can create a port-channel on two physical interfaces that will uplink to a VSS pair. However, the command is not recognized. What am I missing? I've tried executing "channel-group #" on the physical interface and tried creating the port-channel 1st and neither commands exist. I haven't seen it listed anywhere if it is only available after a specific piece of ASA software. If it is the software what version at a minimum I need to upgrade to? Below is an output from a show version

Cisco :: Moving A Port-channel Without Taking Down Traffic?
Mar 6, 2012So I have a current port-channel between two 6ks that I need to upgrade. There's too much traffic and the port buffers on the SUP7203B sort of suck. Microbursts are causing overruns like mad. Im going to move the 2x1gig port-channel to a 6724 and make it a 3x1gig port-channel. The switches carry production traffic across the link to the tune of about 400 meg during the lowest load time. Initially, I thought that I couldn't move the port channel without temporarily taking down the link but I think I have a workable solution now. Has anyone done this successfully before? Im curious what others have done. Also, to make matters worse, the existing port-channel is 'mode on' and I want to migrate to 'mode active' in the new channel

Cisco WAN :: Load Balance Of 3750 Port Channel?
Jul 17, 2011What is the load balance method of 3750 port channel ( by source ip , or by source mac ) to diver traffic to paths? I have tried to use 10.242.104.101 and 10.242.104.102 as source ip, it will travel to the same link (G0/1) within one port channel (G0/1+G0/2). Howerver, if I later use 10.242.104.109, then this time it will traffic to G0/2 link. What's the concept behind.

Cisco Firewall :: ASA5580 Port Channel To 6509 VSS?
Dec 17, 2012Anyway, here's the situation I'm trying to configure several VLANs on my ASA to uniquely allocate to contexts, the VLANs will be trunked from my VSS. Unfortunately I'm not clear on how to achieve this, the configuration guide for 8.4 talks about multiple contexts and routed setups all which don't appear to apply exactly. I've configured the port channel at both ends and I've configured sub-interfaces on the port channel and assigned VLAN IDs. These sub-interfaces are then allocated to the contexts to set 'ip address' etc. I've not been able to successfully test this configuration and I am concerned that it is incorrect..
View 1 Replies View RelatedCisco WAN :: 40Gb Port-Channel Between 3750-x Switch Stacks?
Apr 9, 2012I have a customer that would like a 40Gb port-channel between two 3750-x switch stacks. When I try to activate four 10Gb ports in the channel, they go into error-disable. However, I am able to create a 20Gb port-channel without issue. I have had my configurations verified to Cisco best practice.
Is there a limitation on the amount of throughput that the 3750-x can handle? According to the data sheet the 3750X-48T can handle 101.2mpps, based on two 10Gb uplinks so if my math is correct then a stack of two 3750X-48T should be able to handle 202.4mpps.

Apr 22, 2012I 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.
Cisco WAN :: 6500 Port Turns Amber After Unbind Channel
Sep 12, 2012We have one cisco core switch 6500 series which was configured portchannel on several gig interfaces. This port is used as a trunk to enable communication between VLANs. The VLANs is where several high-end servers/hosts reside.After we disable / unbind the portchannel, the port turns amber. The following is what we did on the interface
1-no switchport command
2- make the port as access mode #switchport mode access
3- shut and no shut
4- clear arp
5- clear mac
what else can we do on that particular interface. It is just on that particular interface, the rest are ok.

Jan 22, 2012I'm doing some L2 cleanups across mutliple 6509E environments and I've found something consistent that I can't find in documentation. On all my pairs of 6509s where I have FWSMs bundled (6509-A has FWSM-1 is Slot 1 and 6509-B has FWSM-2 in Slot 1) I also have a port channel 305. Obviously when I do a "show run" or "show int desc" I don't see anything in slot one. It's a service module. But the port channel is referencing ports 1/1-6. And it's all in service/up. I was about to delete this as I thought it was some leftover config (TEST 6509s) until I went and saw the same things on our PROD 6509s. Is it cosmetic? Necessary? Can I delete it as part of my audit cleanup? Don't want to mess with it even in TEST without some information. Nothing on google that's clear and I can't find anything on CCO.

Cisco Wireless :: 5508 / WLC Port Channel Host Flapping
Oct 9, 2011I have setup LAG for one of our 5508 controllers and have connected 4 of the 8 ethernet ports to a 4507 switch. After configuring 2 port channels on the switch we are receiving a host flapping error between the port channels and it seems to be causing a serious slowdown on the switch. When I shutdown one of the port channels the error goes away and traffic returns to normal. I have the same configuration at other locations with the only difference being the switches used are 3750G-12S and I do not see the host flapping error. It appears to only be a problem with modular switches.
One other thing of note: I read a Cisco white paper on LAG and it suggested creating the port channels over 2 different modules. For example, put ports G4/24 and G5/24 in port channel 1 and G4/25 and G5/25 in port channel 2. I tried this but I still got the host flapping error.

But the ports on the core g7/11 and g7/12 keep shutdown and when I do show interfaces port-channel 15, it show the interface is shutdown.
