I've created a new VLAN 2 for my 10.1.2.0/24 network with the VLAN interface 2 ip address 10.1.2.10, my intention is to route 10.1.2.0/24 traffic to my 10.1.2.1 by creating the access list and route-map.
I've configure my test pc with a static ip and my gateway pointing to 10.1.2.10 (VLAN 2 gateway) , i'm not able to route to 10.1.2.1.
I have a WCCP Configuration on a Catalyst 3750G and a IronPort Webappliance. I have configured this situation many times before with cisco asa and ironport wsa, but with a switch, this is my first time.
VLAN 147 is a transportation vlan between the cisco switch and a hp coreswitch with the clients and servers behind the hp coreswitch.
VLAN 147 IP Address of the Catalyst is 172.30.47.1
IP of the IronPort Appliance is 172.30.47.10
IP of the HP Coreswitch is 172.30.47.2
Plan is to redirect the webtraffic coming from clients and servers from the 10.0.0.0/8 net behind the hp switch to the ironport wsa. In have configured these settings.

I'm due to replace a stack of 2 x 3750 switches very soon with 2 x 3750Gs. These 2 current switches are the VTP server for a small domain. I have put the config on the new switches switches and I made it a server and used the same VTP domain and password etc and got the VLAN info ported over.Now I did this a while back and noticed the switches are in transparent mode with a revision number of 0, I need to set this back to server and swap the switches out but the revision will be lower than the client switches (around rev 200), what do I need to do?

The two stacked Cisco 3750G Access switches on a particular floor in my coy just lost connectivity to the distribution Switch this morning. This meant that all Users connected to it couldnt connect to the Internet nor access local network resources.I couldn't ping the Switch IP, I couldn't also access the Switch via Console port. Each time I tried to gain access via the console port, I keep getting "Authentication Failed" message.What should I do next? How do I gain access to the Switch?

View 5 Replies View RelatedI am about rip and replace my current 3750G stack with a 3750X stack. I have trunked over vlan and vtp info and implemented a config so it should be ready to go other then moving cables onto it. However one thing I want to correct with our current setup is that the root bridge on our vlans including vlan 1 is on a separate set of switches that we control, however I would like this new stack to be the root bridge for all of our vlans. It will be the central set of switches that all other switches trunk into. I have pre-set higher spanning-tree priorities for each vlan on the new stack so I expect as I move lines into it that the tree will be re-calculated with it as the root bridge. I've ensured that there are no root guards on any of the other switches trunks and priorities are all at default levels for each vlan. Should I enforce root guard on the trunk interfaces of the new master stack? Most of the trunks are port-channels to the other switches - do I need to set root guard on the Port channel interface or on the individual ports that make up the Port channel? On both? Any other recommendations in regards to implementing spanning-tree with the new stack? I know using port channels eliminates a lot of potential for loops but not every trunk is and I'd still like to have spanning-tree on.

View 1 Replies View RelatedI currently have Cisco 3750G which is currently live and active and fully populated and only have remote access.
I have an additional same switch which I would like to stack. My initial plans were to have 2 GIbit etherchannels, but I came across the option to Stacks both switch with each other.
When I do a show switch on the live switch its set as a Member: [code]
I would like to add the new switch to the stack without losing the config for the switch which is live. I understand that the highest priority of the switches becomes the Master but as the live switch is Priority 1, would chancing this affect the switches config, or would it lose connection at all?
Also when I plug in the new switch and it reboot how do I ensure it becomes the slave without rebooting the live switch?The cables on the switch do they have to go to port1 on the live switch and port 1 on the new switch or can they be port 1 and port 2?

I have a 3560 switch with 1 VLAN (VLAN 10) where I need to make ports:
1-10 as isolated (can't contact each other)

23 as promiscuous (server that ports 1-20 need to get to)
24 as promiscuous (WAN router where ports 1-20 need to get to and the remote servers).

I am going to change a running 6500 switch. I am missing a best pratice doc for changing a cisco switch configuration. My question is if a startup-config has an error (due to typo mistake, or due to comands not supported on latest IOS) and I do copy tftp startup-config then what will happen ? I want to make sure when I do "reload" the switch then it should boot normally with the latest startup config !

I am uploading new configurations to my Cisco 3750 stacked switch and noticed that after the load I cannot log back into the switch because my password somehow was changed. After performing password recovery and getting back into the swtch, I noticed the configuration register was 0xF. I have never seen this before. The config-register command does not seem to be supported to change it back to factory default. The switch is on a ship which has several power hits when they switch power from shore to ship power.Can this cause the configuration register to change? What is the best way to change the configuration register?
