Re: EtherChannel alternatives(??) [7:33187]

2002-01-26 Thread Darrell Newcomb

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,

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...

EtherChannel alternatives(??) [7:33187]

2002-01-25 Thread John McCartney

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!

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.

Re: EtherChannel alternatives(??) [7:33187]

2002-01-25 Thread John McCartney

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...

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.   ;-)

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..

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

In all sincerity, I am curious as to the thought process. the why is
generally more educational than the what

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.

Regards,

Will Gragido
