Cisco WAN :: 2960 Can't Ping All Devices On Remote Subnet
Sep 27, 2012
I have 4 x 2960 switches in a remote site. These are managed by an NMS in our DC, the NMS IP ends in 35.100 with a /23 mask.
When they are first booted, the switches are visable to the NMS, but after a week or 2, 3 of them drop connection to it. If you reboot them again they are fine. You are able to log onto them form thier local router and use a Radius server which is in the same subnet as the NMS.
The odd thing is, whilst they can not ping the NMS, they are able to ping any other addresses in the 34.0/23 range.
The config on the one that does not lose connection is the same as the other 3 and I have also rebooted the NMS.

I have an GRE Tunnel across my head office and remote site with multiple subnets using cisco 1841 routers.I can ping most of the devices on the remote side, but I can not ping certain devices.These devices respond to ping requests on the local LAN, but not through the WAN link. If I change the IP of device than it start responding. I am using same gateway and mask on these devices.The remote site is running classic STP on switches with distribution switch being the root bridge.

I have a new 3560G to set up a small network for a remote site. I configured the vlan and an SVI as the gateway. The switch is also the DHCP server for the LAN. I configured Gi0/2 as L3 port, connecting to the nearest neighbor. My network runs EIGRP so i advertised the routes into the EIGRP process. The switch forms EIGRP neighbors and learns all routes in the enterprise network. The problems I'm having now are: 1. The switch learns all routes in my enterprise LAN and can ping devices in the enterprise LAN, but I can’t ping any interface on the switch from the enterprise LAN. 2.

i have 2x 27 subet ( we will call first /27 fip and call second /27 sip) we assign sip subnet to our virtual machine and we do not want assign ip from sip to our physical node and we wan assign ip from fip subnet to our physical server, because we want sip can not spoof physical server ips, so when we create vlan in our switch we set port 1 and fip and sip subnet access to this vlan in this senario can my virtual machine spoof our physical node ip ? some one in my datacenter technical team told me we should create vlan for fip and create a seprate vlan for sip then set vlan fip and vlan sip access to switch port #1 is it right? if it is ok can some one give me the commands for this senario which create 2 spetare vlan and access them to port siwtch #1 for exaple? we have cisco 2960 48 port ,

One is my HOME the other is my CARAVAN SITE. both networks are working fine independently, the problem occurs when i join the networks togetherI need to connect the said networks together in order to view my IP cameras which are dotted all around the campsite, i need to be able to view these from HOME.The problems i am having is DHCP servers are stealing clients from the other sides and directing them to the wrong gateway.please see below network map (these routers are all running DDWRT)Below is another network map which someone on another forum told me to do but its still not working. (DHCP servers are still clashing and still stealing clients)by the way, on both of the network maps all routers are connected with the LAN interface. someone told me to connect certain routers with WAN and it didn't work, or it was not explained correctly.Also please note that assigning clients with Static IP's is completely out of the question due to most of the clients being campers who come and go.

I'm currently taking a networking course and was having some difficulty answering the following questions and could use a little clarification.Question: When pinging a non-existent device on your subnet, why doesn't the source node issue a ICMP echo request.My thoughts on this was because there was not a receiving node therefore any ICMP packets were not issued.Question 2: when pinging another non-existent device but not on your subnet, why doesn't the source node issue a ICMP echo request.

we have some devices on the network which cannot be secured and we need to isolate from the rest of the subnet.Our switches are Cisco 2960.Is it possible to via an ACL local a specifric port down to only allow traffic from specific MAC addresses? I've had a go at this myself but not been able to make any progress. The traffic type is TCP/IP.

An 1841 is conencted to the internet by DSL, it works fine. I have added it to the 10.98.8.x subnet off a 3750 switch.When I connect other devices to the same switch port, I can ping/browse to them fine, but when I connect the 1841 I can only ping it from the 3750, not another subnet connected to the same router.

I have a Netgear modem/router [DGN1000] (192.168.0.x) that serves as a the router for network 1 and also as the internet gateway. I have a Cisco [E4200] (192.168.1.x) router connected to the Netgear modem via the WAN port on the Cisco. This serves as the router for network 2.
DHCP is turned on for both routers. I can access all devices on network 1 using any device o network 2 including the Netgear modem configuration page, but I cant access any device on network 2 from network 1. Is it possible to have access to devices from both networks? [URL]

I have a Linksys WAG120N Wireless-N ADSL2+ Modem Router. The firmware version is V1.00.12.I run a Windows machine attached to the router which has a certain sub network address. On that same machine I run a Virtual Machine with Linux which has its own address, 192.168.1.102. I've been noticing that whenever I shut down either machine and then turn them back on later, they acquire another address, which makes it annoying for me to make them communicate between each other (by, for example, trying to load a webpage hosted on the VM from the physical machine) without knowing the actual address, which, as I said earlier, seems to change every time.
I'd like to know if there's a way (with my router model) to configure it so that the sub network address of both machines remains the same, no matter whether or not they've been shut down and restarted.

We want to use an ASA as a pure routing device. Our network has several internal subnets (10.1.x.0/24), and we want to be able to reach them from outside and to allow access between them.
We have a defined a VLAN for each subnet range with the same security-level, added it to an Ethernet port and made the Ethernet that acts as outside as a trunk, and defined it as the global routing.
We cannot ping any of the subnet IPs defined in the ASA from outside nor we can ping it from the internal IP addresses.
Configuration:
: Saved
:
ASA Version 8.2(1)

I have been tasked with replacing our company eSoft router with a Cisco ASA 5505 with the upgraded security license. I have been working on the configuration for a couple of weeks now, after reading hundreds of forum posts, watching youtube videos, and endless google searching, and despite my best efforts I am still having an issue I can’t figure out.
I have a couple of subnets, that when the ASA is connected, I cannot ping, nor can they get to the internet or our Exchange server. At this point I’m not sure if it’s an access rule issue, NAT issue, or DNS issue.
Here is the network layout:
ASA: 192.168.0.2 (Primary Gateway)
192.168.0.0 (Primary facility, ASA is the gateway)
192.168.2.0 (Second facility, connected via Verizon point-to-point)
192.168.3.0 (Third facility, connected via Verizon point-to-point)

Background: I have a couple of ASA 5510's I'm going to put in our lab environment. I have restored them to default config and set up the m0/0 interface with an ip/mask and started the http server. My lab environment is on the 10.45 subnet and my .com corporate environment is on the 10.40 subnet. I've also setup DNS and, from the ASA, can ping anything in the 10.45 subnet.
The problem, is that from the ASA, I can not ping the internet or my 10.40 subnet. And vice versa, I cannot ping the ASA from my 10.40 subnet. When I bring up a regular server, there is no special configuration I need to do as those subnets talk to each other and nothing is restricted.
Is there something special I need to do go get it to work? I tried adding a access list to allow icmp, but that didn't seem to work.Oh, and I'm getting to the ASA by RDPing into a lab server (on 10.45) then putty to the ASA.

I had both a Westell 7500 and a Linksys Router working fine and had my 360 setup as an extender for Windows Media Center so I could stream TV, Music, Movies, etc from my desktop to the 360. Then I switched my modem/router out with a Zyxel PH5001Z
So now today I noticed that I can no longer find my desktop through the XBox. I have adjusted my firewall settings on the modem itself, even completely disabling it. UPnP is enabled for the 360 and the device is showing under my device table. At first I wasn't able to ping any network devices but after creating an ICMPv4 Firewall rule it worked fine. I've confirmed the XBox IP Address through Network Map, the Device Table on the modem and through Network Settings on the XBox. I've diabled my modem firewall as well as Windows Firewall, completely and I still can't ping my XBox or set it up as an Extender.
I have the XBox connected wirelessly using WPA2-Personal and it's operating in 802.11g/n mode.

I have an 871 set up at home with 2 VLANs, both of these vlans present a strange behavior where an user is unable to ping/contact another user on the same subnet, however if users are on different subnet it seems to work [code]
According to the troubleshooting that I have done, the issue seems to be with the broadcast traffic, ARP request/reply do not reach another host on the same subnet (wireless to wireless or wired to wireless) however if the wireless device iniciates the connection to wired, it works fine.
I have tried to enable proxy arp on the different VLANs and BVI and different combinations but no sucess in order to get traffic across 2 wireless devices on the same subnet or a connection that is iniciated for a wired client to a wireless one.
I tried enabling and disabling dot11 arp-cache but no luck.

My employees connects with a cisco ipsec vpn client to asa1,They can connect the network 192.168.1.0/24 from the employee location.(192.168.3.10 - 192.168.3.15) ip pool.Some people must also have a connection to the 192.168. 2.0/ 24, is it possible when they connect to asa1 with the ipsec vpnclient and that the 192.168.2.0/24 network also is avaible.

I have a network with 3 sites that are on different subnets. Each site has an ASA Right now, I am only able to connect to the ASA that is connected to the subnet I am connected to.I want to be able to connect to the ASA that are on the remote subnets on the address of the inside interface.The sites are connected all together by site-to-site VPN.Is there any way I can achieve that without opening the outside interface directly on the Internet?

I have a weird problem which I have already submitted a TAC ticket about. When users authenticate through AnyConnect into our HQ ASA 5510 they grab an address from 172.16.254.x. What we have been noticing intermittently is that when logged into our network through the client they are unable to access their resources at one of our remote offices which is connected over l2l to the HQ ASA. This problem just started randomly a week ago and we have been working with Cisco trying to create a solution.
My quick fix is logging into a device at the remote office which is trying to be accessed and pinging the gateway of the virtual subnet for AnyConnect users. When I ping 172.16.254.1 it goes through after a few dropped icmp packets and then the issue is resolved for about 8 hours or so.

Main Site allows communication from Remote Site via VPN to Windows ServerMain Site also has a secondary subnet that communicates ONLY through internet but NOT to the Windows Server.Sonicwall 192.168.168.x is main siteRemote Site is 192.168.0.x connecting to Main Site to access shared folders on serverSecondary subnet at Main Site is 192.168.0.x using Windows XP PC's. They are accessing a linux server at 192.168.0.215 which Main Site has no access to.VPN remote ip's are 192.168.0.x - they can successfully access the Windows Server at 192.168.168.100 BUT NOT 192.168.0.215.GOAL: Want to connect Remote Site to Secondary subnetWilling to make router changes or whatever is necessary to get Remote Site to access Secondary Subnet with the only exception that the Secondary Subnet REMAINS.VPN DHCP is turned off but willing to turn it on.Willing to make the Linux Server 'discoverable' on the Windows Server. Don't know linux at all but another co-worker set it up and can make changes.

I recently installed a couple of Cisco Aironet 3600 Series Wireless Access Points at a remote site. While I was at the site everything seemed OK, The clients were able to get connected to the access points, the guest network worked fine, I could SSH into the access points, and I could ping them. The problem is when I went back to my home site I tried to SSH into the access points through an ASA IPSec VPN Tunnel and it couldn’t find it. When I try to ping the access points they “time out”. I can ping and connect all other addresses (via RDP, HTTP, etc..) on the same subnet which should rule out an access list problem. A couple of notes to be aware of:
The WAP’s have the Autonomous IOS installed (Version 15.2(2)JB) The WAP’s are connected to Dell PowerConnect 5724 (Not by choice.. We are a Cisco shop, these were already there and have plans this year to replace)
I can ping and SSH with Putty to the WAP’s from the local subnet I cannot ping or SSH from a remote subnet to the WAP’s. I can access all other IP’s and Computers from a remote subnet.

I just got PI1.3, I'm new with it, and I don't know how to add devices. I have an 4500-X, an 3850 and 12 pcs. 2960S.
I see that are some out-of-the-box templates, but when i try to deploy, for example "medianet perfom" in Devices box I got "no data available"

I'm getting currently installing a full Valcom IP sound and clock system , along with all new Cisco 2960 gig ps-l switches. All devices run off of POE. In the past, I have read that most AP's only draw approx. 12.5 watts (va's). But you must take into account length of wire to add your additional draw which puts you at the 14.5 they auto draw. My question being that the clocks I have auto draw 15.4 watts, which is eating up my 370w of power on my switches. The spec sheet on the clocks show only a power consumption of 4.5 watts. So today I turned a few ports down to 4.5 watts and everything still worked fine.. Any experience by chance with Valcom devices or just turning the power down on devices in general? I can imagine that a clock is drawing enough to care about the length of the wire run.

We are using Campus Manager 5.2 with LMS 3.2. We have 100 devices and all 100 devices has been successfully discovered in Common services in all 100 devices are showing in DCR.When we check in RME we have found all 100 devices over there.
But, in Campus Manager we got only 95 devices. out of 88 WS-C2960G-24TC-L 5 switches are not showing in Campus manager. we have added the same manully ( manually included & Ecluded all 5 devices in Campus manager) and start the data collection, but no result.
After data collection it is showing not managed by Campus Manager when we check ( Show all Included devices option).

I have a Cisco 2960-S Switch, It is connected to a jack in the building to check the settings, Interface VLAN 1 has an ip, there is a default gateway, Any host connected to switch can access the network resources. But the problem is that I have to use Serial Cable to configure it. I cant ping or telnet into it from any other device. PC's are on different subnets/VLANS.
Basically this switch is connected to a port in a different switch, Do i have to make a trunk?

I'm trying to configure a 2800 series router. .I'm consoled in and put a basic config on the router (see attached). After putting this basic config on, I plugged it into a small unmanaged switch, changed my laptop's IP and plugged it in the switch also. I can't ping the router from the laptop and vice versa. This is the second switch I've tried this with, so it must be.The first switch, I installed at location, connected a cisco cable to it and a local server, so i could remote in and finish configuration. In that scenario, I had plugged the switch into a managed switch and had the same result as I'm getting now--can't ping IP addresses (can't ping the switch's IP, not can it ping local IPs).

I have several cabinets with top-of-rack N2K's attached to N5K's via FEX's. 9 cabinets with 2 switches each.
Recently I added 3 more cabinets to the mix, for a total of 12 cabinets with 2 switches each.
I can get into the new switches and see the FEX's and configure ports, etc. but no device I attach to the 'new' N2K's is pingable over the network. I can take the same device, same cable, and attach it to a legacy N2K talking to the same N5K's, and it immediately joins and is pingable over the network
