I have a 3500 XL switch with the following default gate IP address that i need to clear from the switch but not quite shore how to remove it.
I've removed the customer original Ip for security reason as this is an open discussion forum and just replaced with 1.1.1.1

imagine I want to make VLAN200 workstations communicate like the show in the attachment. What would be the default gateway to be configured in the workstation? If I configure 192.168.1.1 as the default gateway (R1 interface fa0/0) is this right?That could be possible because the switch should be configured with command "ip default-gateway 192.168.1.1"?

I have two ISPs. Each is on it's own subnet connected to the 6509 MSFC/Switch. FW1 is on 100.1.100.0/30 and FW2 is on 200.1.200.0/30 subnet. My goal is route all traffice going to the Internet from subnet 10.133.3.0/24 to FW1 and all other subnets across the organization to FW2. I am not sure if I need to use ACL / Static route combo, or just a static routes or ACLS?
View 5 Replies View RelatedWe have two catalyst 3560 switches running c3560-ipbasek9-mz.122-58.SE2.bin They are connected using etherchannel using gi 0/21 - 24 interfaces.
on 3560-1 switch, there isn't any ip-default gateway or ip route configured. It only have 1 interface vlan configured.
on 3560-2 switch, there is ip default gateway configured along with 1 interface vlan.
What i dont understand here is that, i can reach out to other subnets from 3560-1 switch in which the routing is not enabled?
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

View 5 Replies View RelatedI have a bit of a mystery on my hands. I had a whole campus of Cisco 3750's cache a new default gateway. Example
Cisco3750#sh ip redirects Default gateway is 10.10.10.1
Host Gateway Last Use Total Uses Interface172.16.0.5 10.10.101.179 0:00 185749 Vlan1172.16.0.76 10.10.101.179 0:01 47254 Vlan1192.168.0.154 10.10.101.179 0:00 183090 Vlan1
My question is what generates a IP Redirect packet or how does the switch know what to change the gateway to? As in my case the changed gateway was a dead IP address. So I am at lose how this happened. I this case the Host IP's are network management servers conducting polling.
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.

I'm trying to configure an IPSEC VPN + tunnel for multicast data. When the default gateway is set on the router (1841) it works fine but if I only set a route to the IPSEC peer via our gateway then the tunnel fails to come up. The end point is to a 3rd party. [code]
I found that if I add a static route for the tunnel destination via fa0/0, the public facing interface, the tunnel comes up..ip route 10.23.4.2 255. 255. 255. 255 FastEthernet0/0
and I can then ping the tunnel IP at the far end - 10.23.0.5.Why would that be? Is there a better way to do this without using a default route??
I 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.
Recently we observed that newly installed WS-C3560CG-8PC access switches are able to communicate without a default route or default gateway.The 3650 switches are used as a layer2 access switch behind a layer3 distribution/core. They have only the management VLAN configured for IP with a single address.
The ARP table looks like there is an implicit proxy-ARP request sent for any IP address.
We definitely have no configuration whatsoever which would explain this.
Is this a new feature? We don't observe that with the older 2960-series...
Here is a brief trace of what's happening (debug arp):
host41#ping 1.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:
Sep 20 14:44:06.706: IP ARP: sent req src 10.1.8.41 1833.9dc9.wxyz,
dst 1.1.1.1 0000.0000.0000 Vlan1

[code]....
The mac address if of course the mac address of the layer 3 interfaces of the distribution switch, no surprise here (proxy ARP is turned on by default).
Why is the 3560 sending out proxy arp requests without being told to? As far as I understood proxy ARP on Cisco IOS it only means it will reply to a proxy ARP request but will not send out proxy ARP requests by default.
Using Network Assistant in XP, plugged ethernet cable to first front port and keep getting "Failed to get Default Gateway. Check your security settings to make sure the current Java Virtual Machine is not prevented from running commands.", I have tried reducing secruity to nothing but I still get the same problem.
I also have an official cisco console cable and tried that, but Hyperterminal just does not pick it up when plugged in. I have left the IP dynamic, turned off all netowork adapters apart from ethernet, set the baud rate etc... correctly, still no joy.
We have a Cisco Catalyst 4506 running: "Cisco IOS Software, Catalyst 4000 L3 Switch Software (cat4000-I9K91S-M), Version 12.2(25)EWA14, RELEASE SOFTWARE (fc1)" I have configured the default gateway as: ip default-gateway X.Y.116.65, However, when I do, "show ip route", it only shows the 3 connected networks and states "Gateway of last resort is not set". The Command "ip classless" is not set. I read on some blogs that this might explain the issue. However, when I go into config mode (config t), I get the following output.
View 9 Replies View RelatedI 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 had setup a lan infrastructure with 5 3750 stack swithes. In these 3 of them are in one stack which is acting as access switch, 2 of them in another stack which is as core switch where all the SVI is configured. Now, when i tried to ping from our edge pc which is connected in access switch to default gaeway, which is configured in core switch, the ICMP is getting delayed . But when try to ping from the same edge pc to another user PC, it is getting less tahn 1 millisecond icmp replies.
why icmp is delaying to default gateway , but working with another edge to edge pcs without any delays?
We have two MPLS circuits managed by two different suppliers, one carries VOICE the other DATAWe are to decommision the VOICE MPLS and have increased the bandwith of the DATA MPLS to carry VoIP traffic too.
At both of our sites A & B ,devices connected to the LAN have a default gateway of the VOICE providers Cisco 2600 router , which then goes into the LAN switching. (see diagram)So what I am trying to achieve is toto simply replace these 2600 routers from the VOICE MPLS provider with our own so we dont have to change the default gateways at both sites.
Testing
Our Cisco 2600 routes are plugged into each LAN switching environment with two subinterfaces configured, one for voip and the other for dataThe problem is from the router and respective subinterfaces we can get to the other sites destination without any issue, but if for example a user is at site A with Ip address 10.16.11.12/16 they cant ping the VOIP subnet at site B 10.3.11.0/24. But If a ping is issue from the Site A test router then the 10.3.11.0/24 subnet is reachable but only on the 10.3.12.0/24 configured subinterface.So i guess what Im saying is 10.16.0.0/16 from the LAN needs to be able to get to 10.3.11.0/24Note at site A 10.16.0.0/16 & 10.3.12.0/24 can communicate no problem and at site B 10.207.0.0/16 & 10.3.11.0/24 can communicate no problem.We are using IP routing, should we be using route-maps?
We have a 6509 series of core switches and 3750 series of L2 switches, There is no default gateway or any static routes to any IP.VLAN 1 is made admin down and another vlan is used for all communication here in this environment
Attached is configuration for reference But still I am able to take telnet or SSH. I want to know how telnet or SSH or tacacs authentication happens without any static or default route.
i am facing a problem when the client vlan is commmunicating with the default gateway on the core 3750-x.
ios in 3750-x core is 3750e-universalk9-mz.150-2.SE.bin. But, client to client communication is happening without any dealy and icmp is less than 1 ms always.
When try to ping default gateway of client vlan, it is getting delayed (variable icmp delays). Is this an ios bug?
My ISP is changing out all the ADSL routers in our area and they have blocked the Default Gateway Address, so we can not access it via Web Browser. This is frustrating because they changed our Wi-Fi password, instead of just keeping what we had like an Einstein. They said they did it because of Hackers

Client is having 1 file server running small business windows server 2003. Server is not configured with domain, it is working only on workgroup. We have around 15 users who are using that server as file server only. Now my main question is do i need to configure DNS server in that server?we also have internet connection running (have problem in that also, will explain next time) with wireless router to connected with switch. So do I need to setup dns in server also or just put static ip (I prefer static then dhcp) & dns server from ip will be ok? If I put dns which I got from ISP, so will it create any problem with using those file from server?the second question is..

We had a core switch (4503), distribution switches and access in our network and consists of many vlans. Almost all vlans uses DHCP Pools. But for few vlans DHCP is not yet configured. Recently one of the rogue user in vlan 1 gave the corresponding interface vlan ip of core switch (gateway) as his ip and caused a prolonged network outage for the vlan. Any way we are going to seggregate vlan 1 into different vlans, but before that we need a temporary plan to block such kinds of attack.What are the possible ways we can avoid the network outage problem even if a user gave the gateway ip to the machine?
View 3 Replies View Relatedhrome threw me a DNS lookup failed. I go into my network settings and I noticed that I had limited connectivity. It would switch between no network access and no internet access every few seconds. After a bit of fiddling around, I got it to connect through assigning myself a static IP. This isn't exactly convenient because I use this computer on multiple networks. When I try to have it on automatic IP, I get no IP address or default gateway when I do an ipconfig /all. It would appear that my router quit assigning my laptop an IP for no reason whatsoever. DHCP is enabled on the router, and all other devices work fine. What could possibly be the problem here? I'm 99% sure it's not an IP conflict either. It's not being MAC filtered because I'm on the thing right now posting this through a static IP. It's not my A/V because it's worked great in the past. Perhaps I should also mention it occasionally says "unidentified network" instead of the SSID

View 9 Replies View RelatedI have a Cisco SG200-08p that's acting up. After setting up 2 larger 200 series switches I pulled this out for its config. I changed the default password and assigned the new static IP address of 192.168.0.103, that's it. The settings applied and worked normally but after rebooting the switch it reverted itself back to the default ip of 192.168.1.254, it retained the new password. After this happened a few times I upgraded the firmware to the latest version, reset the device to factory settings and applied the new address again to have the same problem. It doesn't matter if I reboot the switch in the management interface or physically. Is there a problem with having a zero in the third octet (that would be lame)?
View 6 Replies View RelatedWe have a server connected to a 3560 switch which in turn connects to 6500s. The gateway interface is on the 6500. We will be changing the 6500s so the mac address for the gateway will change, however the IP address will remain the same. As we change out the 6500s the uplink connections to the 3560 will go down. This will flush the old mac address from the 3560.When the 3560 removes a MAC address does it update servers so they have to relearn the correct MAC address?
