View 7 RepliesI 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.
What 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.
View 1 Replies View RelatedI 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.

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
View 1 Replies View RelatedI set up a port-channel trunk between a acess switch 3750 ( int gi2/0/1 and gi2/0/2) and Core 6509( int gi7/11 and gi7/12).
On the both the 3750& 6509 I configured:
interface Port-channel15
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 100,103
switchport mode trunk
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.
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 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.

View 4 Replies View Relatedhow 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.
We have a stack of switches that is at the max number of members allowed in the stack. Problem is we are running out of port density and need to add more ports. So instead of adding a whole new stack I would rather replace 2 of the 24-port swicthes with 48-port switches.
If the two 24-port swicthes we are removing are stack members and neither of them are the stack master, I should be able to replace the 24-port switches with the 48-port switches without bringing the master offline? If the new 48-port switches are running the same IOS version as the current 24-port swicthes, they should add themselves to the stack?Would I have to tell the new 48-port swicthes what switch numbers they are replacing in order for them to be added to the stack since we are at the max number of members?Also since the 48-port swicthes are replacing 24-port switches will the master give the 48-port switches the configuration for only the 24-ports?
I'm unable to assign port E2/1 to port channel. I get following error:

I have just been setting up a WISM2 in a test lab and for some reason the Supervisor is not creating a port channel on my 6500 as suggested in the WISM2 Deployment Guide. WISM2 is installed in an appropriate slot (according to same doco) and have attempted reset to factory defaults, removing and power cycling several times.

We have tried once by removing the physical interfaces from the port-channel group but we lost the connectivity to the secondary switch. Any step by step procedure without losing the connectivity between switches.

So 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

So 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

Anyway, 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 RelatedI 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 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.
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.
