View 2 RepliesWe have purchased two new Nexus 3548 switches. According to documenation the Nexus 3K does support vPC. When trying to enable the feature I get this:

We are running software version version 5.0(3)A1(1) and it looks like the latest version is 5.0(3)A1(2) so that's not much of a difference.Am I missing something here?
We have 2 x C6506E and 2 x C3560-48's, they are all interconnected via port channels at 2Gb per channel. The 6506's are running CEF but the 3560's are not (The 3560's carry all our server traffic).When I do a show CEF on the 3560's it says %IPv4 CEF not running. There does not appear to be a global command to enable CEF on these switches.Is this an IOS version option or is not supported on the hardware platform?

View 3 Replies View RelatedI am going to upgrade a number of catalyst 2960s-switcher to the latest IOS- version. The best solution for me would be if all the switches could be reloaded at the same time to shorten the maintenance-windows. So my question is: If I run the upgrade (archive down load -sw) before the maintenance-windows WITHOUT the reload-option, will then the switches continue to run without interruptions with the current IOS- version and config until I run reload manually?
View 3 Replies View Related1)For 3650X I found some contradiction in the Q&A about feature set LAN Base vs IP Base:
LAN Base: Can I do static IP routing ?
LAN Base: SVI => is this for intervlan routing ?
2)For 2960, there are 2 flavors (LAN lite and LAN BASE) Q: Can I do static routing on one of these flavors ?
I am using Packet Tracer to simulate Cisco networking.As the existing IOS of the 3560 and 2960 switch are in older version which has no new feature in new IOS, how to upgarde the IOS of Cisco switch at Packet Tracer?

Is the feature "event logging" that is present on ACS 4.2 with the option to "send all events to the windows event log" no longer supported in ACS 5.2?
View 1 Replies View RelatedWhat is supported in terms of running a mixed feature set in a Cisco 3750 switch stack.We are looking at setting up a stack consisting of 5 x 3750V2 and 2 x 3750G. Due to a requirement for full EIGRP we need the IP Services feature set. Is it a supported configuration to run with 2 or 3 switches running the IP Services feature set as stack masters and the others running IP Base? I understand that if stack master priorities were set these switches with the higher feature set could manage the stack and offer IP Services accross the stack. If we were to lose all of the switches running IP Services the stack would drop back to IP Base.I am looking for guidance as to if this is a supported configuration and not in breach of licensing? Is this likely to cause any problem other than above now and for future IOS releases?

I have no problem to configure DHCP server on BVI 1 and VLAN 1 ( native VLAN ) interfaces, but there is a problem with other BVI's and VLANs. Maybe this feature isn't supported? Maybe DHCP server feature is supported to work just with default BVI and native VLAN?

View 3 Replies View RelatedI am facing an isssues with 7609 for LAN switching , based on LAN (VRRP/HSRP) feature.Actually we are having ES+ cards (on 7609) and we are using multiple groups(say 350 vrrp groups) running on the router . the routers are connected as router 1>>> mux(which is working as switches)>>> router2
my questing are
1. does their will be "multicast packets" (for VRRP/HSRP group) "from backup router to Master router", when in stable state( ie when Master and backup are already chosen) , or the packet from backup to master should be unicast.I know for sure, the packet from master to back is multicast packets denstination to Multicast IP packet and To MAC address.I am not sure but I think from backup to master it should be multicast
2. what is frequency of these packets( from backup to master)
3. As i have multiper group on a single interface ( we are using q-in-q), when the connectivity from router's is broken, then does all the groups will muticast their active roll in the lan sengment "at once" or it will be in a groups say 100 groups at once, and after few ms few 100's and sone ( as is on OSPF or RIP)
we are in between troubleshooting I hope we get the ans( Actul problem we are seeing in the router's that we have 2 ports on active routers and 2 ports on standby router , but we are not seeing muticast on 1 port on standby router where as all other 3 ports are seeing multicast packets) [code]

We've recently started using some 2911's on our network running IOS 15.0(1r)M9. I noticed, much to my frustration that the OIDs with the MIB RFC1213: ip RouteTable1.3.6.1.2.1.4.21 are not supported.
Any alternative MIB for viewing routing table information via SNMP on any of these devices running a similar IOS?
one of our switches (WS-C2960G-24TC-L). When I try to turn on the lanbase-routing feature using sdm prefer lanbase-routing, it gives me an error (Unknown command). I tried "sdm prefer ?", and lanbase-routing wasn't there (only qos, default and dual IPv4 & IPv6). The switch is running on image C2960-LANBASEK9-M version 12.2(50)SE5.We have another switch (WS-C2960S-24TS-L), running on image C2960S-UNIVERSALK9-M version 12.2(55)SE5, and I can enable lanbase-routing feature. If I upgrade the WS-C2960G-24TC-L to version 12.2(55)SE5, will it be able to do inter-vlan routing? Or is the switch itself totally limited to VLAN configuration only?

View 2 Replies View RelatedHad problems with voice quality on VoIP with 4500 series switches and the qos dbl feature (which gets enabled by the auto qos feature)?? I have had a couple of customer complaining about voice quality and our voice team spent a lot of time investigating; I had ruled out the network infrastructure because it was all QOS enabled. The voip people came up against a blank so I looked at the network once more and disbaled dbl with hope more than anything else. Mysteriously the voice quality issues the customer was having have now disappeared. Not sure whether a coincidence (though I have done this on two customers now) or something to with with dbl. There is nothing on this on cco.

View 1 Replies View Relatedcan you stack a 3750 switch over fiber.....the answer is no, but the virtual switching supervisor 720-10G for the 6500 can create one virtual switch using two 6500s...
how can we get cisco to come up with a way for access switches to be stacked over fiber similar to above supervisor? i know of few of my site that would benefit from this...maybe they can come up with a vss appliance, similar to a media converter, to convert stackwise over fiber...then of course, you would need the same appliance on the other end....
