Cisco Wireless :: WISM2 No Port-Channel On 6504-E?
Jan 18, 2013
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.
I 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.
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
Cisco Adaptive Security Appliance Software Version 8.0(4) Device Manager Version 6.1(3)

We have implemented VSS on Cisco 6504-E switches using the 10GE links on the Sup-720-10GE. Two Cisco WLC 5508 controllers are planned to be connected in a LAG configuration, (consisting of eight links per LAG bundle) to each of the 6504-E chassis( Total of four WLC, two for primary and two for secondary). WLC HA feature may be implemented on the primary and secondary WLC controllers using the 7.3 latest code release.
We have some new WISM2 running 7.0.116.0, but now we need to upgrade their license to suport 1000 APs. So I am looking at upgrading the software to 7.2.110.0. We are running WCS at the moment and got NCS with the new WISM2, so going to 7.3 and buying Prime Infrastructure is not an option at the moment, thus we are going for 7.2.
The thing is I can't seem to find much info about this upgrade. Is 7.0->7.2 a smooth upgrade? Do we need to do any configuration changes to the WISM2 or LAP1242? We are running H-REAP, will the change to FlexConnect be affected? I can't seem to find anything regarding requirements for 6500/SUP for running WISM2 7.2, do I need a certain software for that?
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
I want to do the inter vlan routing packet tracer file url...configuration of MLS are as bellow can anyone tell me why vlan on switch0 can not ping vlan on switch1. [code]
Is it possible to configure a Cisco 2801 router with Multipoint Port Channeling? A service provider dropped a 4.5Mbps ( 3x T1s ) to one of our customers without any equipment. They assume the CPE responsible. If so, any links to documentation on this configuration. If not, what device will they need to buy from Cisco that can bundle these 3 T1s together then feed it into their router?
I have configured my Nexus 7018 and 5548 as follow (see diag attached).Both 7000 and 5500 are vPC pair(po1and po2). Now I have created port-chanel between 7018and 5548 as port channel PO3 on 5500. Would it give me 20g bandwidth as PO3?or 10g only uplink to 7018? Do I need to config all four 10g links in PO3 on both 5500 and 7000 switches to achieve max b/w and failover?
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?
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.
Create a port channel out of interface 3 and 4 of ASAConfigure 2 sub-interfaces in those Po interface (my inside vlan and the dmz)At the 4948, configure a trunked port channel out of a single interface (funny ), then do the same in the second 4948Connect ASA port 3 to the 1st 4948's single-interfaced port channel, ASA port 4 connects the same on the 2nd 4948.
I need to increase the link capacity of 10GE to 20GE between two Cisco7609, so I feel the need to configure port channel between them, my little problem is that I have a SCE 8080 in the middle of both 7600 currently is configured inline. The SCE has 4 modules 1X10GE-L-V2 (currently in use 2), I was investigated and the truth is that I not found anything concrete about how to configure the SCE to "pass" etherchannel through it? What the SCE needs to support 20GE of traffic? (configuration and software)
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..
I have a question regarding WISM2 DP and licensing.
Suppose i have a WISM2 with 7.0, 500AP license today and i activate WISM2-DP by upgrading to 7.2,Do i get 500 AP capacity for free (total 1000AP) or do i get 250APs on each WISM2-blade ?
If i get 500APs for free, why is Cisco selling an expensive licensed 1000 AP WISM2 ? I better buy a single-plane 500AP-WISM2 and upgrade it myself then...50% profit.
Is this the same for a WISM2-300 (supporting 300 APs) ?When i activate WISM2-DP here, do i get an extra 300 AP or an extra 500 APs ? Or 150AP on each blade ?
I having an issue with WCS and the new code 7.4 on my WiSM2 blade. When I try to refresh configuration from/to controller it fails. I just upgraded from 7.01 and it worked before the upgrade.
Is this not supported?
I am able to change configuration from WCS to the WiSM2 and it works fine just cant copy config.
I 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
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 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. [code]
I'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.

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 have installed WiSM2 with ver 7.4 and Bonjour works great with instruction provided, But…… 2 problems. I cant get it to work on the same subnet. (odd since the whole problem was not able to work across subnets), More important the new Code function / password function on the airplay wont work. I get the code on the projector, but the ipad never pop up the login box it just errors out.
