Technology at Geneseo Community School District 228
Yesterday I replaced three more Catalyst series switches at the Middle School. This stack of switches originally had four switches, one 24 port and 3 48 port Catalyst 3500 XL and 3550 series switches. I was able to replace these with 3 Catalyst 2960G’s, with one of the units stacked together acting as a single 96 port switch. With this completed I now only have the switches at the Middle School server room left to swap out and configure. For the most part the configurations are identical to the switches being replaced, although the trunk protocol must be switched from the proprietary Cisco ISL vlan protocol to dot1q as it is no longer supported by the 2960 Catalyst series. Overall this is okay as the ISL vlan protocol is slower and less compatible so moving all switches to dot1q is preferred anyway.
The last set of a switches will be slightly more complicated to swap as one of the switches is configured to partially operate in a DMZ zone relaying information to our Firewall/filter. Another switch houses all the VLAN data and I would like to switch this over to a different switch and basically switch roles of one switch making it the core and retiring an older 4908 switch. I should be able to switch all switches this week and finish the last step of switching roles of the core in June or late May as soon as school dimisses.
Overall moving to 1000mbps switches makes a big difference in network latency and overall speed is noticeably improved as the switch comes online.
