Re: [c-nsp] Stacking 3750X vs diverse 4948E

Yes - the 5548 does routing. We have 2x 5548UP's with the Layer 3 daughtercard in our small corporate DC. It does routing, yes, but you need to be aware of caveats around the feature. I suppose you could say that about any Cisco switch, but bear in mind that NX-OS is aimed and targeted at th

If you're trying to eliminate STP, try Flexlink... which the Nexus 5010 doesn't support, but the 5500 series (apparently) does. 3750X does support Flexlink it seems. *Skeeve Stevens, CEO* eintellego Pty Ltd ske...@eintellego.net ; www.eintellego.net Phone: 1300 753

How about Nexus 5010s. I think they bundle them for less than 2 x 3750X . We have both but the 3750s are used where we needed L2/L3, the 5Ks for just L2 up to VSS or 7Ks. you can boot them separately and they do LACP / Etherchannel just fine. > 2. Stacking 3750X vs diverse 4948E (David Cou

Re: [c-nsp] Help with ACL Rule

You can't apply two ACLs on an interface. You either need to copy/paste the first ACL into the second (and then add to it) or in newer code you can use object-groups to build the elements and then select which object-groups to put in each ACL, which is not a perfect solution, may be easier to manag
