Cisco Switching/Routing :: WS-C2960S-24TS-L / 4 SFP Ports For A Switch?
Jul 24, 2012I have a got a requirement where a 24 Port Switch should have 4 SFP's and all 4 should be used at a time, So I've chosen " WS-C2960S-24TS-L"
The transeiver should be GLC-LH-SM, so kindly let me no whether I would be able to use all 4 ports at a time or not.
Cisco Switching/Routing :: WS-C2960S-24PD-L PoE+ 10Gb Switch Using 1Gb Uplink
Jan 24, 2013I have configured about 20 of these switches now, and notice in the port listings a TE1/1//1 TE1/1/2 and GI1/1/1 GI1/1/2 uplink port. There are only two uplink SFP+ ports. I now have a reason to install with a 1Gb uplink to the Core. I am using a GLC-LH module at each end. I did configure the TE1/1/1 port for the uplink. Does not work though..Do I need to configure the two GI1/1/1 and 1/1/2 ports for uplink, remove the TE configuration for the uplink to work? Using the UNIVERSAL code with a LANBase license.

With this new configuration the switch has rebooted again.Why on a standalone switch the stack is rebooting my system?Is it any feature to disable the stack?

May 7, 2011I just have recently been experiencing some dropping off the internet.. My phone company has been out here and has done tests, and changed out my wireless modem with a new one, switched me to a new high speed port.. cleaned up the cables outside my house.. installed a new jack.. and we have yet to solve this intermittent dropping and reconnecting... I am starting to wonder, if not anything else with my outside line.. is there something else causing the problem. I switched my channel from 11 to 9.. *my neighbor is on channel 11* thought maybe his was interfering with mine .I am using WPA, I have disabled the power adapter from "saving power" in the adapter settings..
When the internet does drop off the DSL light on the modem goes out, and then comes back on..its not blinking off and on, just off.. then waits.. then reconnects to the net, it's almost like it's refreshing or something every couple of minutes.The modem is a Siemens Speedstream 6520
Wireless Internet Ping Spikes Up To 1k To 3k+ Every Couple Minutes?
Sep 28, 2012my ping spikes to 1k+ all the time, making online games pretty much unplayable. Sometimes I'll lag up to 3k ms and by the time my ping is back to normal, the game is so behind it is messed up forever.I've looked online for days trying to find solutions, and trying all kinds of things. The problem started after i reinstalled windows xp (it actually started right after my power flickered after i reinstalled, but i think that may be coincidence. I'm not sure though.). I've reformatted since then, but the problem still persists.I think the problem might be WZC, but when I try stopping the program like other people have done, my wireless network disconnects pretty soon after. I've also tried just using the intel software, but that didn't work either. It was fine for a while last night after I changed to the intel software, but after maybe an hour or so it went back to lagging.I have Intel PROSet Wifi agn 5100 as my network card. I'm on a laptop. I also tried doing a ping test in command on my mom's laptop, and it never spiked like mine. Is my network card maybe just too old? I got the laptop almost 4 years ago.

Cisco Switching/Routing :: Created Load Balancing Between Two Catalyst 3550 On Couple Of Vlans
Feb 24, 2012I am testing on lab equipment (2 Catalyst 3550 and 1 Catalyst 3560) HSRP version 1 and 2.I successfully created a load balancing between the two Catalyst 3550 on a couple of vlans (11 and 12) on ver 1
now, just adding the command "standby xx version 2" my hosts on the 2 vlans are completely unable to ping the virtual IP def. gw on debugging i checked that msgs are exchangedthe two cat 3550 are seeing each other on HSRP (active / standby roles)the real ip addresses are pingable rebooted the swiches (just as a last resort try)deleted arp chache on hostsremoved the auth on hsrp all of this no effect.
i also tried to modify the priority on the cat 3560 (before he was on both vlans in standby) to make it the active one and with the same config it worked flawlessly.
My only idea is that there is a bug on CATs 3550 (IOS: c3550-ipservicesk9-mz.122-55.SE4.bin) [code]

Cisco Switching/Routing :: WS-C2960S-24PS-L Floods Network
Jan 21, 2013I have three new 2960 switches as listed in the title. I configured them as follows:
192.168.1.215 host: whse-c
192.168.1.216 host: whse-b
192.168.1.217 host: whse-a
Switches B and C flow into A before continuing on into the server room switch (distance issues).All three switches are configured for ports 21-24 at 1000 and set as cisco switches. all other ports are undefined as they have a myriad of desktops, printers and non cisco access points flowing into them. side question - should i configure them as access points where applicable even if they are non cisco? I am replacing three netgear switches that currently are in place and have no known issues other than they are old and the fans may fail soon.hooked up .217. was able to get to it from the network. Hooked up 215 and then 216. All the sudden I lost the ability to tap into the switches, any of them. (I think I had done 215 at that point too, before adding 216. I found out later it took the network to its knees as internet was lost, and the MPLS stopped functioning.
I undid the changes and put the netgears back in service and all was right with the world again. At first I thought it was a bad host name as I had used whse-a on switch C in error. I changed that after this issue.Later that day I put 215 in place. checked it from the network and could get to it just fine. Then I put 216 in service. I lost connection to 215. I could no longer get to the internet from my pc and the MPLS went down again. This time I just unhooked 216. 215 is still in place and working on the network at the moment and not causing issues. (btw these switches are not even in my path from my pc to the internet, just on the same network) tomorrow I am going to try 217 again while 215 is still on the network and see if there are any issues adding that swtich. if I can do so, and there are no problems, is this an indication of a faulty switch? what further testing can I do, have I missed something in setup? If this brings the network down again, why cant i add two of these switches to each other/on the same network path (B and C were not even connected to each other yesterday evening when it went down again).
