Cisco Switching/Routing :: 4507R-E / No ARP Virus - Switch Can't Response Ping And Telnet
Apr 10, 2012
We got a switch issue here for 4507R-E with two sup6l-e supervisor running sso redudant. and we found that sometimes client can't ping through the local vlan ip add on the switch , can't logon the cli by telnet too. In the direct connected network device such as access switch and ASA , can't ping or telnet the 4507R too. when we made a forceswitch to sso standby supervisor from console , the problem solve and everything get fine . after that, we switch angin back to the origin supervisor , fine too.
before we made the supervisor forceswitch , we had check the system cpu usage is 15 - 20 % from console . also we had creat a new vlan 200, attach the notebook to 4507's vlan 200 port , the notebook can't ping or telnet the vlan 200 ip interface too.

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?

We have Four 2960S Switches in Stack. We have created Multiple VLANs. While Pinging from Member PC to Member VLAN IP on Switch, we are getting Higher TTL response & Some ping breaks for One Particular VLAN. While pinging from Member PC to Member PC, we are getting Normal Ping Response.

I need to add another SUP engine on Cat 4507R switch, with a new one. I have old SUP engine running in this switch. Sometime this switch is reloaded without any reason. So we want to add another sup engine for redundancy. What is the procedure to do this & also how much outage time would it cause? Which sup engine will be run as primary and which one should be redundancy?

I'm in the process of upgrading my 4507R core to a new 4507R-E. The old switch has Sup IV engines (WS-X4515) running IOS 12.2(40)SG and the new switch has Sup 6L-E engines running 15.1(2)SG. I'm trying to "move" my configuration from the old switch to the new. Below shows the commands configured in the old switch. I'm trying to determine how to implement the same configuration on the new switch since these commands are no longer available.

last day i went to one client for the installation of C(WS-C4507R+E)
current ios :cat4500e-ipbase-mz.122-53.SG2.bin
there is only one sup engine installed and redundant slot is empty.
I installed one ethernet module in the slot 6 and it get detected working fine. I also want to install one fiber module but that module is only supported by 12.2 54 sg or later ios version.so i need an ios upgrade.
For the ios upgrade I decide to do it through svi interface For that i igive an ip address to vlan 1 (192.168.1.2) and plug cable in gigabit 6/1 and added that port into valn 1.
my laptop's ip is 192.168.1.1 @ this point i faced a rare problem the PING IS NOT WORKING.(switch is directly connected to my laptop).
Then i create another VLAN (2) and add that port into vlan 2 still ping is not getting.last thing i tried is that making that gigabit port into a routed port and result is same.

I have 2 Catalyst 2924 switch in a home lab. Both of them have developed the same problem at the same time (strange). I have tried all that I can think of. I can telnet to them but cannot access via the console port. On a telnet session I execueted a "write erase, reload" on one of them. As I anticipated this threw me out of the telnet session and I presently have no access to that switch.
The console cable is fine, works for all other devices.

We made an IOS doBlades on switch 4507R keep block after an IOS downgradewngrade. Before to do it, the equipment comes with blades 1, 2, 3, 4 and we insert "X4418" and "X4548" on blades 5 and 6.[code]
After we made an IOS downgrade to a cisco 4507R from "cat4500e-ipbasek9-mz.122-54.SG.bin" to "cat4500e-entservicesk9-mz.122-53.SG2.bin" (comes with a redundancy supervisor blade WS-X45-SUP6L-E) the standby supervisor keep disable.We tried with the command "Switch(config)#boot system flash cat4500e-entservicesk9-mz.122-53.SG2.bin" then save configuration and "reload" comand but the switch runs with the "...54.SG.bin" IOS.
We erase the configuration with the command "erase/all non-default", before to apply the reload command insert the "entservicesk9-mz. 122- 53. SG2.bin" using the tftp command.The standby supervisory remains on disable state but the active supervisory runs with the desire IOS. In order to downgrade the IOS to the standby supervisory the active supervisore was removed temporarely (previously the switch was off) to make the standby as active, after that made the same procedure with command "erase/all non-default", "copy tftp://(....122-53.SG2.bin), and "reload" command.
The switch was off and re-insert the active supervisory and turn on the switch, after we made the procedure the blade "WS-X4548-RJ45" marks a fault as follows: [code]
The blades were reset but don't have access to them.

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 read quite a few documents on configuring SPAN on a cisco switch but none of them mention any limitations or any kind of CPU load it can have on a switch. I need to configure this on one of our switches and would like to know if there are any implications related to SPAN.

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'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
[Code].....
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 looked at setting a default gateway for the various vlan interfaces

Today one of our 9 Cisco switches a "WS-C2950S" (we also got 2 other WS-C2950S on same network) stop responding icmp ping packages. When i tried to telnet the switch its network was unreachable but i was able to see its existance from other switches by "sh cdp neig". So i decided to fix the situation on a suitable night time work, checking by console cable or even rebooting the device.
Then i started to wonder... what this could possibly be about?We have like 40 clients behind that switch and there was no communication problem during the problem.
