End user have had problem with IP phones that are connected to 3750 stack; many times IP phones lose connection with CallManager
and the only way to clear this issue is with clear arp command. DHCP for IP phones is configured in 3750 stack.
At the beginning 3750 stack was set a VTP server, and the others as VTP clients, we detected another VTP server switch so we thought that was the problem, but after removing the issue remains. Finally we set all switch in transparent mode.
Base on this we decided to change the software image 12.2(35)SE1 C3750-ADVIPSERVICESK ---> 122-53.SE2 IPSERVICES
I'm going to follow the procedure 3750 Series Switch Stack IOS Upgrade − Automatic .
as it show in the following information there are 4 differents models of 3750 switches, I have already download c3750-ipservicesk9-tar.122-53.SE2.tar
I have two doubts:
1. There is no problem for using this tar file for all models?
2. I followig command is correct for the change I plann to do ?
I haven't notice about the option /dest 1 /dest 2..... I thought it was enough to laod tar file in master.
Currently, only the 2960S does NOT need the "/dest 1 /dest n" command-switch. I have no idea as to why this feature isn't ported into the 3750/3750E/3750X.
any reason for using 12.2(55)SE4 ?
IOS version 15.0(1)SE has a memory leak and it affects any appliance that runs this version. 12.2(58)SE also has a similar (but not the same) memory leak bug. If you want to run 12.2(58) then I recommend looking at the 12.2(58)SE2. If you find the need to run 15.0(1)SE then I'd recommend you stay away from this version like a plague. The fix for this version is scheduled to be out by March 2012.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
