Cisco Switching/Routing :: 3560G Can Ping Devices In Enterprise LAN But Cannot Ping Interface
Mar 31, 2012
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 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!
Config:
HOST ON VLAN 96 IP 10.11.120.99 S/M 255.255.255.240
I have a Cisco ASA 5505 and I have my internal and external interfaces configured but I currently cannot ping from the inside to an IP Address on the outside. I had this setup and working and I have another set of equirement that I am replacing that is working with my service provider so I know it is a configuration issue. When I ping 4.2.2.2 for example I get:
Destination host unreachable
Do I need to add a static route from my inside interface to my outside interfaces?
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
I set this up and I can ping all the gateways but never the hosts. I was hoping I could make these links between 6500's a mix of L2 and L3. Check it out. They are connected in a linear fashion R1--->R2--->R3. I can ping from R1 to R3's SVI4 gateway but I can never ping a host on that SVI4. I was hoping that I could use the port-channels between 6500's as routed links or as trunk links depending on the type of traffic....thought it would ease the migration. I suppose I could always get rid of the port-channels and just make separate L2 and L3 links between the 6500's.
From My Router that connects to Cable modem i am unable to ping website 4.2.2.2I am able to ping all other websites fines.Same website i can ping from my pc and all other switches fine.Router has only 1 ACL thats for NAT.
I wounder if there is any way to ping the local deviceses connected to a network hosted by a Cisco 1921 router? I wan't to be able to ping the device(computer name) but currently cant do that.
I just barely put in a Cisco 3925 on our network. I've configured gigabitethernet 0/2 to live on our management VLAN with an IP address of 10.129.0.31/16. I did a "no shut" on the interface. Everything should be ready to allow me to ping and/or SSH to that interface but I can't. It's really weird because I've done this a thousand times (at least on ASAs). I must be missing something. At any rate, the default gateway of the management VLAN is 10.129.0.1. I can ping that from the router. I can also ping that from my laptop (which lives on a completely different VLAN). But I can't ping the router from my laptop or vice versa.

I'm facing a problem regarding loss of ping packets when i do ping test from nexus3k to another nexus3k connected directly.however there is no error counters on the interfaces on both of devices.the ping failutre is occurring only whenever i do ping test with a large number of ping packets.I don't see the ping loss symptom with default ping test (default ping test is 5 packets).
H/W : N3K-C3548P-10G S/W : 5.0(3)A1(1) nexus3k# ping 1.1.1.2 PING 1.1.1.2 (1.1.1.2): 56 data bytes 64 bytes from 1.1.1.2: icmp_seq=0 ttl=254 time=2.732 ms 64 bytes from 1.1.1.2: icmp_seq=0 ttl=254 time=2.732 ms
I've got a 2621 configured as my main gateway to the internet - right now it's obtaining a DHCP ip from a the ISP's proprietary router set to bridged mode.
As of now, I'm unable to ping the internal interface of the router. I can ping external IP's only, even though I have DNS servers listed, i am unable to resolve host names. I'm running a few servers to which people are able to connect to my web server, among other services. I even have a crypto map setup to another 2621 across the country and can ping all internal ips on the other end... I JUST CANNOT PING THE INTERNAL INTERFACE of the router!!
I've noticed that when I ping the router during it's boot process (using linux un-interupted) I get a response in a very short window, then dies again. I'll post my config below:
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 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 a copper over ethernet connected to an adtran 908e connected to an ASA 5505 with a port 192.168.150.254 connected to the router on the Gigabitethernet 0/0
I can ping to internal and external ip addresses but when a device is connected through the wireless signal then the device cannot ping anything; what could be stopping the device from pinging any ip addresses internal and external?
I posted my current config for the router and ap:

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).
vrf ping is not happening between two pe devices in 7609 router having VS-S-2T-10G modules with 15.1 SY1 IOS version? Is there any commands need to add? between pe devides ldp is running properly and ibgp too. I am doubtful about VS-S-2T module.
[code] I can not ping IP 192.168.1.1 from SWH02. I observed there sth wrong when trunking over SDH. Because when I config int vlan 121 on another switch(SWH04) already trunking with SWH01, I can ping IP 192.168.1.1 from SWH04.
I could not ping 8.8.8.8 and access internet after creating the VPN. Below is my setup and router configuration: [code] From the router 1941, i could ping up to 58.185.149.141 but not up to 58.185.149.140. Since i cannot ping 58.185.149.140, i suppose i cannot ping 8.8.8.8. I am sure 58.185.185.140 is there as i use another PC which is connected directed to the office network instead of through the router 1941, it could ping 58.185.149.140.For your info, the g0/1/0 is connected to the PC while g0/1 is connected to the office network.
My FastEthernet 0/0 interface uses DHCP and got 172.16.2.126 /16. My Ethernet 0/0 interface is my internal interface, it has static 192.168.0.1 /24. On the Ethernet 0/0 interface, I have a PC attached, IP 192.168.0.150 /24.
The router's gateway is set to IP 172.16.1.1
My PC can ping 192.168.0.1 and can ping 172.16.2.126 (both interfaces of my router). My router can ping anywhere on the Internet. But my PC cannot ping 172.16.1.1. Firewall disabled, all security disabled.
I have a cisco 3825 router with two GE interfaces. GE0/0 is connected to a switch through ethernet cable. I have configured the GE0/0 interface with IP address. I have also configured static route for the local network. However, now I can only ping the GE0/0's own IP from the router. Here are the running-config:
hostname Router ! boot-start-marker boot-end-marker ! !card type command needed for slot 2 enable secret 5 $1$4gxa$sykc0mcaxpCIrGc86i1ZE.

The 10.1.52.1 is the current gateway on the 10.1.52.x LAN.
I have a DLink wireless bridge connected to the wireless WRV210 router. All devices connected to DLink can access internet/email fine and can ping the WRV210, however, they can not ping any device connected to the WRV210 router, nor can any device on the WRV210 ping devices on the DLink writeless bridge. All devices are on the same subnet, 192,168.100.X with mask 255.255.255.0. All devices get their address from the WRV210.
I have a Cisco 871 router and I have successfully added a second vlan and connected a switch configured with that VLAN. Anyways, my problem is the device in my new VLAN (vlan200) are able to ping/access devices on vlan1. I do not want this to happen. I read somewhere that the 871 routes between VLAN's by default.
I have a 2811 ISR, a lab unit with almost nothing yet configured other than some IP networks on serial and FE interfaces to ping to other lab routers. And I have one HWIC-4ESW installed, and I amrunning IOS 15.2.I want to set the card as a single routable interface and just have the ports act like switch ports, which I imagine is the default design of these cardsI work a lot with Cisco 891 ISRs so figured it's the same here, assign an IP to interface Vlan1 and all is well. That was wrong, obviously more config is required.It seems there are a lot of differing answers out there, so far none what worked for me. The best looking one I could find said to assign an IP to the Vlan 1 interface, then go to each of the four FE interfaces on the switch module.
I am trying to test the MTU between two 3750 switches I have in the lab. I've set the MTU with the command "system mtu 9000" on both switches and rebooted.
The only connections on the switches are the gig ports connecting the two switches. Each interface is a member of vlan 1.
I am doing an extended ping. I set the datagram size to 2000. When the df bit is set the ping doesn't go through. If the DF bit is not set the ping goes through.
The debug ip icmp shows, 4d00h: ICMP: dst (1.1.1.1): frag. needed and DF set.
Why is fragmentation needed when the MTU is set to 9000?
GigabitEthernet1/0/1 is up, line protocol is up (connected) Hardware is Gigabit Ethernet, address is 0015.2b7d.0d01 (bia 0015.2b7d.0d01) MTU 9000 bytes, BW 1000000 Kbit, DLY 10 usec,
I have 2 routers, one is an Apple AirPort Extreme with a static outside IP address, I also have a Cisco 871 with a static outside IP address. The Airport Extreme connects to a switch on the private network and has an IP address ending in .1. The Cisco 871 connects to the same Private network and it ends in .2. The 871 is setup as a VPN Server. now when clients connect to the VPN they can ping the VLan IP Address on the 871, but they can t ping any other hosts on the smae network. The hosts on the private network can ping the vlan on the 871.
I have a spare Cisco 857w that I am playing around with to learn.I managed to reset it to default, upgrade the ios to 12.4 However for the llife of me I cannot ping this device.
1)Configured 3550 as layer 3 switch and create a default route to 192.168.2.254
2) Configured 2 static routes(for 2 vlan range traffic) and one default route to 192.168.3.254
3) ip pass through is not configured yet, still the public ip is configured at the isp router
1811 static route configs ------------------------------------ Ip route 0.0.0.0 0.0.0.0 192.168.3.254 Ip route 192.168.1.0 255.255.255.0 192.168.2.1 Ip route 10.0.1.0 255.255.255.0 192.168.2.1 3550 static route config -------------------------------------- Ip route 0.0.0.0 0.0.0.0 192.168.2.254
Testing results 1)All lan communications are working fine(inter vlan also), ping to all servers from router is getting and ping to outside public ips are getting from router,but not getting ping from switch 3550 to 192.168.3.254 and any of the public ips(internet).
I am connecting a 2600 router to an ISP. Interface 0/0 is connected to the ISP using DHCP. Interface 0/1 is connected to the inside providing DHCP services to the inside. At least it should only be providing DHCP services to the inside. I also have a public static IP that is NAT to a private static IP. Everything is working except the computer on the static IP. From the router I am able to ping inside and out from each interface. I am able to ping both interfaces of the router from the computer on the static IP but I cannot ping outside the router. If I do a debug all I see a reject for the gateway of the static IP but it has “mobile IP” in the text string. Not sure what mobile IP is relating to. Networks are as follows:
0/0 DHCP 10.X.X.X 0/1 192x.x.x Static 75.X.X.X no ip dhcp use vrf connected ip dhcp excluded-address 192.X.X.1 ip dhcp excluded-address 192.X.X.2 ip dhcp pool CLIENT
I am trying to config the following setup in the Cisco 1841. Able to ping the IPs of Vlan1(FE0/0/1), Vlan2 (FE0/0/1) and FE0/1 IPs from corresponding networks. But packets are not flowing to other side.
We have configured a Cisco ASA 5505 with AnyConnect access. This works great. However, these users cannot seem to ping devices on the private network. We have configured all devices on the network with a 10.10.10.0/24 address space. The inside interface of the ASA i 10.10.10.1/24 and the VPN return addresses are 10.10.10.50 - 10.10.10.65/24.They users can utilize SSH and Oracle or MySQL calls but cannot seem to ping. Obviously, I am over looking something.
I'm trying to set up a Guest VLAN for wireless at a client site, and I feel like I'm missing something small in the configuration, since I can't ping any of the VLAN interfaces from my laptop when the address is statically set to something in the 172.20.100.x range.
I've pasted the configs for the ASA 5505 and the 6 switches below for convenience. Near as I can tell, all should be well. The ports are in trunking mode, the "show cdp neighbors" command returns the proper information, VLAN 100 exists on all the switches, etc.
I have a vlan defined in FWSM for server farm there is a one server with two IP addresses and teaming has done on it how ever from FWSM i am able to ping both IP addresses but from core 6509 switch i am only able to ping one ip address. from FWSM show ARP command displays the same virtual mac addresses against both IPS of the same server.
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
