We have gone through the migration last year and it was a smooth process. Below are our procedures:
1. Prepare wism-2's in lab: 1) upgrade code, upload ssl certificate and webauth bundle. 2) take one existing wism-1 configuration backup and modify the configuration file using a text editor. We only needed to modify these configurations: add more dynamic interfaces from other wism-1 modules(or enlarge the vlans for existing dynamic interfaces), system names and prompt names. This method works for us as all our wism-1 modules have similar configurations except for IPs and VLANs. 2. In maintenance window, just swap the wism-1's with wism-2's, then modify mobility group configurations with the new wism-2's mac addresses. Everything should continue to work. WISM2 have special requirement about SUP IOS version(I think SXJ1 and above). Double check it on CCO. We are not using VSS for WISMs. --- Dennis Xu Analyst 3, Network Infrastructure Computing and Communications Services(CCS) University of Guelph 519-824-4120 Ext 56217 [email protected] www.uoguelph.ca/ccs ----- Original Message ----- From: "Danny Eaton" <[email protected]> To: [email protected] Sent: Wednesday, July 31, 2013 11:49:26 AM Subject: [WIRELESS-LAN] WiSM-1 to WiSM-2 migration strategy.... We just got two pair of WiSM-2's for migration. I'd like to talk (off-line, if necessary) with anyone who has recently gone through this, as to pitfalls, lessons learned, and what not to do. I'd like to make this easy on myself, if possible. Thoughts are - currently 6 WiSM-1's in 6506-E's with Sup-720/3C and 2 4404's running 1,400 APs (a smattering of 1252's, primarily 1142's and 33502's) with 3 SSID's (4 when eduroam comes online fully) New hardware is 2 WiSM-2 pairs. Questions will be - VSS, or no-VSS (pros and cons)? VLAN/subnet size? IPv6 caveats? Issues with iDevices? Android? Thanks in advance... Respectfully, Danny Eaton Snr.
