In 3750 switch,I have configured intervlan routing.I have three vlans Vlan 10,vlan 20,Vlan 30 and I have assigned IP address for that Vlan.In vlan 10,I have connected one systen gigabitethernet 0/1 interface.From my system I am able to ping vlan 10 ip address but I can't able to ping other vlan ip address (vlan 20,vlan 30).Is it possible to up the protocol for all that time.

Our servers are hosted at the Main site, site office A access to the Main site for Internet and servers. We are thinking NextG to take over when the link between sites goes down.
To start with, what is the configuration for 3750 at Site A and the Main site:
1) Trunking for both switches
2) Routing
3) the automatic failover configuration for the switch at Site A.
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?
View 1 Replies View RelatedI'm fairly new at trying to create isolated network segments on Cisco switches. What I'm trying to do is have multiple isolated paths that originate from my v Sphere infrastructure travel through a layer 2 link, v LAN, up to a MLS, and ultimately out to to the internet through a firewall. Each sub net might ultimately have a number of hosts on it, but I don't think the make up of those hosts will matter here.
My initial thought was creating v LAN tagged port groups on v Switches on my v Sphere infrastructure. Physical connections will go from my ESXi hosts to the 2900 series Cisco switch connected to trunk ports. Both v LANs would be configured on the switch but not assigned to physical ports. The physical connection to the 3750 would also be a trunk port connection from the 2960. The 3750 would have SVI's created that are attached to VRFs that would control route traffic. This might be totally wrong but from what i've read it seems to be going down the correct path I think.
Two part question, is this the best way to go about designing this network? If so I seem to be really struggling with the SVI/VRF part. Every time I create an SVI all of my hosts on the 10.10.10.x network can ping them, regardless of which v LAN they're on.
I just cannot seem to isolate the 172 network.
I'm trying to configure a mirror port on a 3750. This configuration needs to replicate data from local ports, but I need that also act as a regular access port.
With the initial configuration, SPAN port, there is no problem, all the data of the configurated ports is replicating in the configurated port. On the port configurated as mirror there is a PC connected for audio recording. When the port is not operating as SPAN there is communications without problem over the LAN. But when I configure the port as SPAN, communication is interrupted.
Here is the actual configuration:
SWITCH1-PISO7#sh monitor session 1
Session 1

Type : Local Session

I am building a new network and intended on using the min-link feature on my port-channels between a 3750-X series switch and Nexus 4k.
However reading further into this it seems this feature is only supported on higher end models. I cannot find any reference to the min-links feature in the 3750-X configuration guide. Is this an available feature?
The 3750-X model is WS-C3750X-24T-L running IOS 12.2(55)SE3 IP Services
My thoughts is that the is only an LACP supported feature so I may not see the command until I have entered an LACP specific command on the port-channel but unfortunately I do not have a 3750X to verify this on at present.

Since Avaya phones do not run CDP, how does the phone know which DHCP pool to pull from to get its IP address if the PC is connected to the phone.
Let's say I have a interface config like this

cisco3750(config-if)#switchport mode trunk
cisco3750(config-if)#switchport access vlan 126

And two DHCP scopes configured on the switch. What keeps the phone from pulling from the wrong scope?

I'm looking at adding a Cisco 3750-X switch running c3750e-universalk9-mz.122-55.SE1 (IP base license) into a stack of 3750-G switches running c3750-ipbasek9-mz.122-55.SE1.bin Given that the version and feature sets are the same I don't forsee any compatibility issues. Would there be any reason why a universal image wouldn't stack correctly with other switches running the single .bin file?
View 9 Replies View RelatedWe have a stack of switches that is at the max number of members allowed in the stack. Problem is we are running out of port density and need to add more ports. So instead of adding a whole new stack I would rather replace 2 of the 24-port swicthes with 48-port switches.
If the two 24-port swicthes we are removing are stack members and neither of them are the stack master, I should be able to replace the 24-port switches with the 48-port switches without bringing the master offline? If the new 48-port switches are running the same IOS version as the current 24-port swicthes, they should add themselves to the stack?Would I have to tell the new 48-port swicthes what switch numbers they are replacing in order for them to be added to the stack since we are at the max number of members?Also since the 48-port swicthes are replacing 24-port switches will the master give the 48-port switches the configuration for only the 24-ports?
some of our switches have the switchport mode trunk command configured between the 3750 switches but other 3750 switches connected to our 6509 core switch do not have the switchport mode trunk command to permit Vlans from going across the swtiches instead it has an ip address and says no switchport what is the difference between does two. Is trunking used only for Layer 2 and L3 is used to route interface vlans?
View 2 Replies View RelatedI have a network with a Catalyst 3750 as the main switch and then some Catalyst 2960 switches that are plugged in to that. I have a server running windows server 2008 with a couple of virtual machines running in Hyper-V. I created 4 VLANS listed below and gave the 3750 the following IP Address.I would like the 3750 to only be configurable from VLAN 40 but currently every VLAN can connect to it, I noticed in the standard web page settings there was a setting for "Management VLAN" but it was set to 1 and would not let me change it, I kinda assumed that was for the management port in the back.-Now the tricky part, I was trying to set up routing between the VLANs and so far I have only been able to get a sort of "all or nothing" routing to work. I can turn IP routing on and add two or more VLANs to the routing and it works fine. But what I was hoping to do is create a couple of "junction vlans" that would only route to one or two other vlans. For instance, I wanted to create a VLAN 100 that routed to VLAN 20 and 30 but nothing else. I also want to route VLAN 1 just to VLAN 30, and so on. I am able to do each one of the cases but only one, it seems like the switch only supports one "routing table" am I missing something or is this just a limitation of the switch?

View 2 Replies View RelatedI have a network with several catalyst 2960 switches and one catalyst 3750. I have created two VLAN and set up the proper routing and everything is working fine there. I have a client/server application that used multicast in the initial start up for the client to determine available servers, the issue is one of my clients is on a different VLAN then the server. I am able to route the multicast using MVR as long as both the server and the client are plugged into the 3750 by creating a static route, making the server a source port and the client a receive port. Unfortunately I need the client and the server plugged in to different 2960s. My question is how do I establish multicast routing between the two and perferably do it dynamically (always route multicast traffic from one VLAN to another).
View 2 Replies View RelatedI have been looking into this for a while and I can't seem to figure out why my 2nd vlan is not able to connect properly to the net.
My switch has 12 ports where my devices connects directly, they are all on Vlan 1 and they all work perfectly. on Port 12 I have a dlink router that is connected to a cable modem. the dlink router has an Ip address of 192.168.0.20
I created a second vlan (vlan2) and enabled dhcp relay on it. then I assigned port 9 on the switch to (vlan2)my laptop which is connected to port 9 seems to get an ip address fine and able to ping only some devices on my network (vlan1) and is not able to go out to the internet. I think it has to do with the routes. [code]

The 3750 switch I have runs C3750E-UNIVERSALK9-M, Version 12.2(55)SE3 on a LAN BASE license.
The first thing I have done is to order for a license upgrade to IP BASE which would give the support for OSPF routing.I do not see much of an issue with the Interface configs, however, I am not too sure about replicating the routing config on the switch.
My question is can I run the commands as shown for the OSPF routing on the switch? If not, can I get suggestions on how best to set this up on the switch?
For intervlan routing, Is 'IP routing' command enabled by default on a 6500 series switches based on the IOS?and on 3750 switches, do we need to enable the "ip routing" command manually for intervlan routing?
View 1 Replies View RelatedI am using a 3750 as a default gateway for multiple Vlans on a few 2960 switches. The trunk lines are configured and working and I have assigned ip addresses to each of the Vlan interfaces on the 3750. My issue is that I can only ping the ip address on the Vlan interface of the 3750 if I have a working computer plugged directly into the Vlan on the 3750. I only have 3 vlans on the 3750 that have hosts directly connected (vlans 2, 10 and 40) the other vlans ( 20 and 70) don't have any clients plugged into them on the 3750 but the hosts reside on 2 different 2960s that connect via trunk ports. How do I keep the vlan interface on the 3750 switch pingable when I don't have hosts directly connected in that vlan on the 3750? (yes, I have enabled ip routing on the 3750)
View 5 Replies View RelatedI have a simple design with 3750. I configured a route-map which define a next hop. I defined this route-map on a policy on a vlan interface.When I test some ping and a debug ip policy and it seems that my policy never match.Is there any mechanism that prevent the switch from using PBR? I think of CEF .
View 5 Replies View RelatedIn our datacenter we have a 3750 stack with IP base image. I have enabled PBR and reloaded the switch. Show sdm prefer says i am using default template. The reason i want to use PBR is that we have 2 firewalls on the same work and want to be able to have granular control over which gateway out of the network they use but still be able to access all internal resouces accross wan and locally.
Created access list to identify traffic:
access-list 10 permit 10.2.3.59 (test workstation on vlan 3)
Created policy:
route-map TestASA permit 10
match ip address 10
set ip next-hop 10.2.0.3
Assigned policy to the user vlan3:
ip policy route-map TestASA
Results:It changed the default gateway to the above gateway but i could not access any resources on any other vlan, could not access resouces accross wan.
