In my setup , i have one core switch 4506, 3750 access switches and 4948 server switch.i have created the mngmt VLAN in every switch.the problem is i can ping the every device mngmt ip from any internal network,but my server switch mngmt ip i am not able to ping.trunk link is configure between the core and server,access switches.What is the problem with 4948 switch?
View 7 RepliesCatalyst 6509E Switch running IOS version 12.2. Created a new VLAN layer 2, created it layer 3 with an IP address. Issued the state active command and the no shutdown command. when doing a show vlan, shows in the list and active. When doing show int vlan xx, shows as down. Need to get it to be up, have attempted to assign a port to that VLAN in hopes it will come up, but still no go.
View 5 Replies View RelatedIn my core Switch,there are 2 v LAN(V LAN 1 & V LAN 2)my switch is Cisco 4948,so be default ip routing is enable in it. My all servers (DHCP,HTTP,HTTPS) are in v LAN 1 & internet is also in v LAN 1.
My requirement is that v LAN 1 user should not communicate with the v LAN 2 and vice versa. But the v LAN 2 users need an access of all servers and internet which is in v LAN 1. How to configure the access-list. I have try on Packet tracer which i have attached.
note:v LAN 2 user should get the IP from dhcp server which is in vlan1.
Current Situation:We are able to reach server IP -10.203.206.40 from our 4948 switch vlan 10.30.1.0/24 through the Layer 3 interface between 4506 and 4948.
Requirements
==========
1) Now we would like to add one more L3 interface between 4506 & 4948 for redundancy purpose.
2) Make available Vlan 540 in 4948 from 4506... need to create two trunk links between 4506 & 4948 and allow vlan 540.
I cannot boot IOS, when i reload this switch it go to ROMMON. I try to uploand IOS but it still has problem. i think i may wrong some point during i did uploand.
This is problem

I have got a new 48port Cisco catalyst 4948 switch, which I configured as a VTP client and connected to Cisco 3750 which is a VTP Server (this switch is on production network). I connected port g1/0/48 from 3750 to port g1/48 on 4948 through a straight cable and made both ports as trunk port (I also tried through cross cable). The problem is these two switches are not detecting. For testing I connected a PC directly to one of the port on 4948 (making that a switch port) still the LED on switch didn’t glow up. Is there any special command needs to be run on 4948 switches to activate its physical ports?

View 3 Replies View RelatedI performed an upgraded on a 4948 switch and for some reason the switch kept booting with the old IOS. I was not sure if I needed to change the boot sequence but I performed this upgrade on some of our other 4948's and no issues.I eventually deleted the older IOS version and left the latest version on and reloaded switch and now switch only boots in rommon.I managed to configure the ip info and tftp server ip etc and using the following command as suggested in the rommon help, but it keeps coming back saying 'file not found', when I have checked the file does exist in the tftp server and in the tftpboot folder.

I have two networks at two sites with a dot1q trunk between the two L3 switches at both sites (no routers involved)
SITE A - Cisco 3750 L3 - VLAN ID 50
10.10.50.0/24
SITE B - Cisco 3750 L3 - VLAN ID 50
10.20.50.0/24
I would like to extend the SITE A VLAN to SITE B so that I can move hosts from SITE A to SITE B without needing to change their IP address but the vlan ID is already in use. Obviously the easy solution is to change the VLAN ID for one or other of the sites but both sites contain hosts that run 24/7. Is there a way to join two VLANs with different IDs together.So for example I create a new VLAN 60 at SITE B and associate it with VLAN 50 at SITE A.
I 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]
I recently set up a small photography business and am trying to get a Cisco 877 and Cisco SG300-10 switch to talk to each other.
What I want is for the Cisco 877 to handle the internet and the SG300-10 to handle the local network,
I have set up 2 vlans in trunk mode on the switch and want vlan2 to manage local traffic and vlan3 to handle the internet.
I have got the 877 connecting to the internet what I dont have, traffic going to vlan2 on the switch from the 877
Look at the running configs for the switch and the router and tell me how to get the vlan on the router to pass traffic to the switch. In a nutshell I am inserting the internet into the switch but am not sure how to progress. I have the c870-advipservicesk9 image file on the router.

I have an environment of 3 X 3560G of which I have 1st switch-CORE(f0/10) connecting to the VPN router(CE) interface-f0/0. Remaining 2 Cisco 3560's(Access) are connected to Gi0/1 and Gi0/2 on the 1st switch-CORE via gi0/1 . On all three switches I have created multiple VLANs and assigned ports to these VLAN. The switch to switch connection is trunk allowing all VLANs created on all these 3 switches. Now the issue is how I am going to have all these VLANs routed through single interface on the routeri-e f0/0, as all these subnets will communicating to remote site over VPN. What should be default gateway on the 2 Access switches and the CORE switch, also what static route should be on router to reach all subnets(VLANs) created on these 3 switches.
I have read inter-VLAN routing i-e creating sub interfaces on router but dont want to proceed with that and looking for any other way to have my VLANs talk on all three switches and then are accessible to remote site ove VPN?
I'm having some problems setting up vlans to talk to each other on a 3550-12T switch. Its quite a simple setup I have, but I need to split my network up.
Currently I have a network of 192.168.25.0 255.255.255.0 I want to create a new vlan network of 192.168.30.0 255.255.255.0 So I have configured my vlan1 (default vlan) to have an ip of 192.168.25.250 for getting to the management page
I have created a vlan2 of 192.168.30.1 255.255.255.0 ?I have a port 10 linked to one of my 3560G's?In port 9 which is on vlan2 I have my pc plugged in with a static ip of 192.168.30.50 from the router I can ping any device on 192.168.25.x.
I can not ping 192.168.30.1 (which is my vlan2) nor can i ping the PC.
I have enabled ip routing But I dont have a default route, this is becase we don't have a router on the network.
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)
11-20 as community (need to contact each other like a normal VLAN)
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).

View 3 Replies View RelatedI am having trouble after creating a management vlan (99) on a 3550 switch.I have configured the vlan (99) and given it an IP (192.168.1.100) and a default gateway (my router address - 192.168.1.99).I can ping to the switch from a PC and vice versa. The management VLAN IP is fine but now I cannot ping to the router from either the PC or the switch.It seems that just by adding VLAN 99 with it's own IP address has now prevented pings from the switch/ PC to the router ?Due to the fact that I have created a new switch management VLAN with an IP, does this mean I have set up the router as a 'router on a stick' scenario ?

View 4 Replies View RelatedI was trying to configure an SF 300-24 for use in my home and obviously did something dumb. It was working fine. The f/w was updated and I had configured 2 VLANs. VLAN2 was ports 1-6+GE1 for IPTV streaming and VLAN3 was ports 7-24+GE2 and GE3 for the rest of my LAN. I was plugged into GE4 and was configuring the switch with a laptop. GE4 was the only port still on the default VLAN1. I chaged the default VLAN to VLAN3, which forced a reboot and the switch never came back up. Attached is what I see when I connect to the console port: [code]
I can't access to GUI using it's static IP or it's default IP on any port and the console never reaches the point where I can log in. The System light is flashing green but the boot sequence never progresses past what's in the screen shot. I tried to do a hard reset using the recessed button on the front panel but it does not seem to have any effect, no matter how long I hold it down.

I'm having some trouble getting my head round the following but I think it's routing related?
I have a Cisco 3750 switch with the following configured:
interface Vlan1
ip address 192.168.0.223 255.255.254.0
no ip route-cache
[Code].....
The 3750 is connected to a firewall which handles the routing. From the 3750 I can only ping remote networks from the vlan1 interface not from vlan6,8 or 10 i.e ping 10.34.37.101 (remote network) source 192.168.0.223 (vlan1) works but ping 10.34.37.101 source 10.74.10.1 (vlan10) does not? I can ping 10.34.37.101 from computers on the various vlans but not from the 3750 it self.
I looked at setting a default gateway for the various vlan interfaces
I managed to create VLAN 30 (mgmt) and VLAN 888 (blackhole) on this SG 300 switch. Now I've configured ports 1-6 untagged on VLAN 30 and left ports 7-8 untagged in VLAN 1. Port 10 is my uplink to my router, which config looks like this:
interface gigabitethernet10
spanning-tree portfast
spanning-tree guard root
switchport trunk allowed vlan add 30
switchport trunk native vlan 888
If I connect a device into port 7 or 8, I get no IP address from the relevant DHCP server on my router. Thus, I thought I could add VLAN 1 to the trunk, but here's the surprise:
swi01-zg-#configure t
swi01-zg(config)#int gi10
swi01-zg(config-if)#switchport trunk allowed vlan add 1
VLAN 1 : VLAN was not created by user.

The field engineer has a stand alone 24 port 2900 series switch that he has different equipment connected to and are segmented using VLANs. So for example, he's got ports 1-4 assigned to VLAN 10, 5-12 assigned to VLAN 20, 13-19 assigned to VLAN 30 and 20-24 assigned to VLAN 40. He would like all the gear on VLAN 30 to have the ablity to talk to all of the other VLANS, but VLAN 40 should not be allowed to talk with any other VLAN. Trunking would do no good here since the switch isn't connected to anything and you can only assign one VLAN per port.
Is there a way to do this within the stand alone switch? The only possible way I could think of would be to ensure that each VLAN has an assigned IP number (subnet) and doing this through access lists.

I've recently purchased a Cisco catalyst 2960S-24TS-L & setup 3 V LANS 10 (no current IP),20 (192.168.2.1) and 30 (192.168.3.1) to reflect the router V LAN configuration & ip information. When connecting my PC to the switch to test connectivity on (2.1 & 3.1) I'm unable to connect to the the net but can successfully ping GW (int FE0.20 & FE0.30) 192.168.2.1 & 3.1.
The router is an Cisco 1801 & it seems this is where the configuration issue is but I'm unable to figure out how to complete the setup. It has been quite awhile since I've configured a Cisco router.
Ive never had this router connected to a switch so all router switch ports are in the default VLAN1 (192.168.1.2), with FE0 disabled. In trying to get the switch to communicate with the router I made the following router config modifications.
FE0 enabled with subinterfaces configured
FE0.10-currently no ip
FE0.20-192.168.2.1/27
FE0.30-192.168.3.1/27
I have two issues I want to resolve:
1) I do not know what additional steps are required to allow 2.1.& 3.1 V LANs to access the net.
2) I want to disable VLAN1 if possible & use the network IP for VLAN10 (192.168.1.0). I'm unsure how to do this as any change on VLAN1 immediately breaks router access and the router reconfiguration becomes more complicated with changes to the FW ACL etc.
