I have a cisco 876 with, c870-adventerprisek9-mz.124-6.T9.bin. I have configured a VLAN with ID 230, an SVI with IP 192.168.230.1/24 and I have assigned switch port fa 2 to it…

I have created two vlans, vlan 1 data and vlan 200 voice. the issue is that when an on one vlan i cannot ping the default gateway of the othe vlan from my PC. An using sge 2010p switches.
below is my configuration
p route 0.0.0.0 0.0.0.0 192.168.0.1
ip dhcp relay address 192.168.0.100
ip dhcp relay enable
ip dhcp information option
interface vlan 1
ip dhcp relay enable(code )
This would probably sound like a stupid question but it took at least 2 hours of my time so far. I have a 3750 switch where a router and a server is connected. From the switch I can ping the router and server with no issue (directely connected). But from the server I am not able to ping the router. The router and the server are in the same subnet. The router is configured as the default router for the server. I am not able to ping the server from the router either. Here's the output of the ip route from the router. The server IP address is 10.1.200.21 and the router IP address is 10.10.200.1
10.0.0.0/8 is variably subnetted, 8 subnets, 3 masks
C 10.1.30.0/24 is directly connected, FastEthernet0/0.30
C 10.1.20.0/24 is directly connected, FastEthernet0/0.20

I have a 3560G and an ASA FW, for which I am trying to use PBR to append the next hop. The gateway is the switch VLAN address and the amended net hop is the same VLAN interface on the ASA. Trouble is, I can ping the FW from a client, but not the switch. If I remove the route map, I can ping both. Even more strange is this is the case for some VLANs, but not all!

I just got my Cisco SG300 28, but I have some problems getting the routing to work. I get the vlans to get to the router, with the default route. But not getting them to talk with each other. I can ping the IPs from the cisco, but I am not getting traffic to go from vlan 1 to vlan 2. When I try to google, it say that it should do it automatically, and I found no setting for it. It looks like it not creating any route for the interfaces.

View 1 Replies View RelatedI have a design hurdle that I cannot seem to cross. I have two sites and I need the same VLAN to span both sites. I have accomplished this using L2TP but my issue is that I can no longer assign a gateway for this VLAN on the router. The 2 routers are 2821's and are connected with a dedicated fiber run.
Ant recommendation for how this could be accomplished? It would be great if I could have the same gateway at both sites by leveraging some sort of bridged interface (BVI so I've heard) but I am at a loss as to where I should start with this. Also, this is not the only VLAN that needs to traverse the link.

I have an ASA that houses 11 VLANs, and I am trying to add a 12th.One of the VLANs is for PCs that have internet only access.The new VLAN will be similar, but for multifunction printers only.VLAN 99 is for internet only and works fine, I can ping the gateway of 10.99.3.33 from any PC in that VLAN.I am creating VLAN 98, modeling it after VLAN 99, and I cannot get a PC in the vlan to ping the gateway of10.98.3.17.Both switch and ASA show the new VLAN 98 as UP, switchport is UP/UP.I have deleted and recreated VLAN 98 a few times, but I cannot get a PC VLAN 98 connectivity.Once it is working on the core switch, I will add it to the trunk to the IDS switches. VTP is not in use, everything is manual. [code]
View 4 Replies View Related 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

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 have set up VLAN 2 on 192.168.2.0/24 with the switch as the DHCP server. The switch is connected to an RV082 router which is at 192.168.1.65/27. Once I figure out what I doing I'll eventually shift that to 192.168.1.0/24 or something similar. So I have my switch acting as the DHCP server for VLAN 2 but I can't figure out how to get it to access the internet.
I found this example to set up the DHCP server:

The RV082 doesn't support trunks AFIK and I'm pretty much a newb at this stuff. TIA. I guess I should get a real router and I most likely will but I'd like to get this working if possible before taking the next plunge.
We have a group of computers on their own VLAN. A router allows internet access while keeping them sandboxed. We don't want them accidentally connect to our production network. We blocked their wireless MACs in unauthorized WAPs. I'd like to do the same thing for their ethernet MACs on our switches, (a mixture of 2950,2960 and 2960G currently testing on C2960-LANBASE-M, Version 12.2(25)SEE2). I've been unable to locate the correct method on google, by searching these boards or in the command reference.
What is the best practice for blocking a group of MACs from accessing a particular VLAN on a network consisting of several Layer 2 Switches?
I'm using Cisco 2960 Series SI, configuring VLAN is not so hard. but i'm having problem with this one. base on the picture above i'm attaching on Fa0/4 and expecting not to ping the default vlan 1. but my question is why i can ping the other vlan since i dont have use any routing?

I am giving the Configuration for both locaitons below :

I've got a 3750x stack set up as my core switch (only a small-ish environment) - I'm shortly going to be deploying an enterprise wireless network with Corporate and Guest SSID's. I'm going to be putting all traffic from the Guest SSID in VLAN 244, and don't want it to have access to any of the other VLANs (1 (Legacy Eqpt), 4, 8, 12, 16, 20, 24, 28, 32, 248 & 252).
IP ranges for all the main VLANs are:
1: 10.0.0.x/22
4: 10.0.4.x/22
8: 10.0.8.x/22
12: 10.0.12.x/22
16: 10.0.16.x/22 etc etc (you get the pattern)
I'll probably give Guest traffic (VLAN 248) the IP range 192.168.10.x/22 (not because I NEED that many addresses, but it's easier for everyone to remember/understand if I keep the subnet masks the same all round). However I also have a CCTV VLAN (252) which already has the range 192.168.0.x/24, which some people in other VLANs WILL need access to.
So my question is: What is the syntax for the ACL on my 3750x (IP base - 15.0.2) to prevent traffic from VLAN 244 gaining access to any of my other VLANs. I'm making a broad assumption here that a layer 3 switch is perfectly capable of supporting that function? I need ALL the syntax for setting up ACL's - I've never done it before
My gateway device by the way is 10.0.4.1, and I do have inter-VLAN routing set up on the core switch (obviously).
