Re: EtherChannel alternatives(??) [7:33187]
One thing to remember if you do the etherchannel for this customer is the src/dst mac pairs and their respective flows may not be diverse enough to offer good load balancing. This is the case for most router to router subnets such as in customer hand-offs like you seem to have. Yes some of the cisco line does src/dst mac+IP (4) tuples which addresses this problem, but not every box does that. I too am interested in why the no VLAN policy in this (hosting?) environment, Darrell John McCartney wrote: It is a policy from our IP-Eng group, can't find it in writting but they tell me it exists. I think because they like to have control. Oh well.

Re: EtherChannel alternatives(??) [7:33187]
Ditto on the no VLAN policy inquiry... But as far as answering your question, I think that you may be SOL as far as aggregation goes... You may not be able to aggregate, but you can use CEF per-packet LB in order to solve the problem of needing more bandwidth... - Original Message - From: Darrell Newcomb To: Sent: Saturday, January 26, 2002 3:35 AM Subject: Re: EtherChannel alternatives(??)

EtherChannel alternatives(??) [7:33187]
Hi all, I have a question regarding EtherChannel. Is there an alternative to EtherChannel that will give aggregation speeds that can be implemented on 6509's. The reason I can't use EtherChannel is that our corp policy forbids VLAN's so hence no EtherChannel. I have a customer who is currently on one 100MB F/E port and soon to be 3 (all using redundancy --HSPR) and they wanted to know if there is a way to aggregate the ports? The first thing I thought of was EtherChannel Any help is appreciated. Have a great weekend and GO EAGLES!

Re: EtherChannel alternatives(??) [7:33187]
You don't need VLAN's for EtherChannel, so I don't understand the policy. Anyways, can you upgrade to Gig Ethernet? Or, use 802.3ad if your switch supports it. GO PATS!!!

Re: EtherChannel alternatives(??) [7:33187]
I forgot to add that we are not using the 6509 CAT IOS we are using the box as a big router (IOS) with many F/E ports. We do have a Gig-E card that we just placed in one but not the other and the customer is concerned about redundancy. I told him we could add the Gig-E to the other one but they would have to work that out with our Sales depart. I think the price for one of those babies is about $30K right, then to pull the fiber to the cabinet cost about $1300 - at least thats what the last one costs us. I appreciated any ideas as I've never implemented EtherChannel and was thinking it may be an alternative. Good luck with the Steelers Steven...

Re: EtherChannel alternatives(??) [7:33187]
Very true. And what's up with that policy regarding VLANs? Does that make sense to anyone? From now moving forward we will not allow any subnets on our network. The network must be flat!! Sounds like they're from the Flat Earth crowd. Perhaps this is the extreme wing of Switch when you can, route if you must. ;-) Steven A.

Re: EtherChannel alternatives(??) [7:33187]
If the customer is rich and has $$ to burn, by all means go get some more gig blades, gbics and run fiber. Otherwise, EtherChannel is still the way to go, and cheapest. Tell the tech/manager who wrote the no VLAN policy that it doesn't apply to EtherChannel. I hate layer 8 of the OSI.. John McCartney wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

I know its a stupid policy, but I have to live by unless I find some other gig but in this economy good luck. Thanks for your input.

not commenting on the policy itself, but I'm wondering if you can explain why the anti-vlan policy exists?

RE: EtherChannel alternatives(??) [7:33187]
Chuck and C0., The policy may be in place in order to curtail some of the innate security flaws that VLANS allow for in network architectures. I have document (somewhere on this laptop), that explains the pros/cons of utilizing VLANs specifically from a Secure Architecture perspective. If anyone is interested, let me know and I will forward it to you.
