This is something that happened as I was setting up a couple of these PoE SF300 switches for IP cameras. We wanted to save a little money so we purchased a few of these switches to daisy-chain onto a couple of our 4507s to provide PoE support for IP cameras that are coming in. But an odd thing happened when I set one up and connected it. I set up the SF300 switch with all FE ports set to access and for VLAN 18 (our camera VLAN). I then configured a Portchannel (PO2) and assigned GE1 and GE2 to it. I defined the allowed VLANs 10,14,18 on the Port Channel Interface definition. I also created an SVI Interface VLAN definition for our management address (on VLAN 10) to be able to SSH into the switch once it's on the network. I did most of this thru the CLI and not the GUI. I saved the config (copy run start) and turned off the switch then deployed it in the IDF closet. I powered it up and connected the GE1&2 ports to 2 Gig ports in the 4507 defined with PO2 - both with MODE=ON. Well, as I found out later, my config changes never got saved and the GE1&2 because trunk ports, so when I plugged them in, They started acting independently. At about the same time another switch we have in our network (that is daisy-chained off a 3750 - 1 trunk port) suddenly had it's uplink put into ERR_DISABLE mode (we also had this occur with another 2 switches with a very similar config - Daisy-Chain). Now , how my config never got saved issue, is not at the forefront of my mind as much as how did a couple of switch uplinks in another building go into ERR-DISABLE.  I know that our 4507s run rapid per-vlan STP+ and that the SP300 only runs Rapid STP, but this is a real mystery to us. If anyone has any ideas for tracking this down, please reply.     ... View more

We have an outdoor AP that we want to bridge to another one that is also outside and connect to our WLC 5508. I see a lot of data for connecting via a layer 3 network, but nothing yet on a layer 2 network (which we run). Can anyone point me to some doc that would explain this? ... View more

We have Layer 2 2960 switches that all connect back to our 4500 core. the core has the Interface VLAN defs. But, in the access switches I can do a SHO VLAN and see all the VLANs in my network, but they do not show up in my running config. The guides all say to use the VLAN global command to define VLANs, but will just entering the switchport access vlan x put them in the VLAN database as well? We also do not have VTP defined. Any ideas? ... View more

        It was unclear to me from the CIsco VPC doc on whether a VPC (going to 2 separate 2Ks) will aggregate both links, and how does the process work for load balancing.    ... View more

Trying to find some documentation as to whether there are any other steps for inserting this new module in our N7K. We have 2 blades in already and 2 Sups in 5 & 6. I'm assuming its like the 6500s, where we just slide it in and the OS configures the global parms for it and the default VLAN. Just want to make sure, if anyone has a link to asny doc, it would be appreciated.                   ... View more
