Cisco Switching/Routing :: Unable To Ping / SSH To Interface On 3925?
Jan 9, 2013
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'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 just receive a new Cisco 3925 with a etherswitch module 24 port :
SM-ES3G-24-P,I successfully boot the switch module and gain access to it.
I found some documentation on CCO but I don't sorted out this small information :,
Switch#sh cdp neig Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge S - Switch, H - Host, I - IGMP, r - Repeater, P - Phone, D - Remote, C - CVTA, M - Two-port Mac Relay
Device ID Local Intrfce Holdtme Capability Platform Port IDRouter Gig 0/26 143 R S I CISCO3925 Gig 2/0Switch#
The Router is connected to the switch module via a HIMI :
The Cisco enhanced EtherSwitch service modules also provide a physical Gigabit Ethernet serializer/deserializer integrated circuit transceiver (HIMI) interface. In the Cisco 2900 series and Cisco 3900 series routers, the HIMI link on the Cisco enhanced EtherSwitch service modules is connected to the router internal Gigabit Ethernet backplane. This link is used for interconnection between other interface cards or network modules attached to the router Gigabit Ethernet backplane bypassing the router host CPU; thus, increasing CPU performance by decreasing CPU processing.
If I do a sh ip int brief on the switch, I have 26 interface but only 24 are physicaly present on the front.The type of the 0/25 and 0/26 are the same : media type is 1000BaseXThe interface gi 0/26 is up up but the 0/25 is down down.

I was trying to enable AutoQoS on my router 3925 GE interfaces, but failed to do so !! But I was able to do so on FE interfaces !! I have Security/K9 and Data/K9 license on this router. Or do I still miss out anything ?? I am on IOS 150-1(M4).
I was able to enable AutoQoS on all my Cisco 2811 and 1841 routers !

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 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'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).

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 cannot ping and end node on my system from my Cisco 2911. I've tried to configure my computer to ping the device and I am able to. It seems the difference between using my computer and the 2911 is that with my computer I am able to set the default gateway as the end node's ip.

i have a device connected to 2960 switch. It is an access port and i could ping the device from other switches , also from outside the lan. But i am not able to ping the device from 2960 switch alone. I suspected and checked the arp table and it was showing as incomplete. I created the manual arp entry and tried pinging but no luck.

I have been working on figuring out a VPN problem on my companies ASA5510. I was accessing the device via: ASDM, SSH using Putty, and even initially with a console cable (also using Putty) using a computer in the networking closet. All 3 of these access methods worked properly for me.I believe I may have inadvertently changed something as of Friday using ASDM. I am mostly assuming this because, as of yesterday I can no longer connect to the device. I actually cannot even communicate with it (ping the interface I normally use to manage, which I could previously ping). No computer on the same subnet as me is able to ping the interface. The device is still accepting VPN connections, dishing out DHCP addresses and everything else it normally does, but I really need to be able to gain access to it again. I am thinking to reboot the device when there is some downtime, in the hopes that ASDM doesn't save to startup-config and only to running-config.

The network is set up like this.
Host -----> 3750 (classic) running IPSERVICES stack ----> 3550 router -----> VPN 3005 Concentrator.
IP routing is disabled on the 3750 (it's acting solely as a switch) IP routing is enabled with an EIGRP process running on the 3550 router that has the network for the 3005 broadcasting.
I can ping the vpn 3005 concentrator from a telnet session in the 3550 but not from the 3750.I can ping between the 3750 and the 3550 vlan management interfaces. Visually speaking it's like this
3750 ------> 3550 [Success!!!!]
3550 ------> VPN 3005 Concentrator [Success!!!!]
3750 ------> 3550 --xxxx--> VPN 3005 Concentrator [Timeout....]
I know this because I tracerout to the 3005 from the 3750 and it resolved the default gateway configured for the 3550 properly but then started timing out.
The 3750 is trunked to the 3550.
3750 is vtp client mode
3550 is vtp server mode
I'm wondering if there's a layer 2 issue involved here as it is a VTP domain and maybe it's not returning properly.

I have a question regarding the 3925 router. In the past on my old 3660's, in order to add a new line to an ACL, I would have to remove the entire ACL and readd it when adding new ACL lines to the list. Is this required on the 3925's, or is it like the ASA 5520's where you can just add an ACL any 'ol time without having to remove/add the entire ACL list?

I am just setting up a simple scenario with a 1841. Server @ 172.31.1.1 cannot ping 172.31.0.254 or 172.31.0.105. It can ping 172.31.1.250. The router can, on the other hand, ping devices on both networks. This is just for testing routing theory so I don't know why hosts on either side of the network cannot ping each other.
I am only using the FastEthernet interfaces on Router 1841.

I am trying to research the possiblity of backing up IOS and configurations from an Etherswitch module, and being able to store the files onto the Host Router's flash (3925 ISR). and then being able to recover that IOS and configuration, in case I have to replace the Etherswitch Module.

I have a 3925 Router with a 48 port switch module (part number SM-D-ES3G-48-P). I have no problem accessing the 3925 Router, but when I go into the 48 port, I get an error that reads
Error Hardware not supported by firmware. Try loading a newer software instead. System Resetting...
I know that the wrong IOS is installed on the switch, but the problem is that this is an endless loop. The switch resets then comes back to the same error. How to get the switch out of this loop so that I can load the correct IOS.

Laptop at site A is set to access vlan 655 and laptop at site B is set to acess vlan 651. I can ping all the devices from one end to the other.I have turned on debug crypto isakmp, debug crypto ipsec, debug crypto ipsec errors but dont get anything at all as output.I have attached the sh run for each router Cisco (1941/K9) and switch (Catalyst 3750) at each site.
