Aug 25, 2012I 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?
Cisco Switching/Routing :: 2960-S - Can't Telnet / Ping Into Switch
Sep 4, 2012I 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?

View 12 Replies View RelatedCisco Switching/Routing :: Ping From Vlan Interfaces On 3750 Switch
May 27, 2013 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

Mar 7, 2012Today 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.
Cisco Switching/Routing :: 4507R-E / No ARP Virus - Switch Can't Response Ping And Telnet
Apr 10, 2012We 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.

Cisco Switching/Routing :: 4900M WS-X4908-10G-RJ45 Port Startup Delay
Mar 4, 2013We have recently purchased 2 x 4900M switches with the following configuration:
2 x X2-10GB-SR installed in port te1/1, 1/2 (optical)
1 x 20 x 1GB RJ45 installed in the top left of chasis ge2/1 - 2/20
1 x WS-X4908-10G-RJ45 8 port 1/2 card in the top right of chassis te3/1 - 3/8
We have te1/1 connecting the 2 switches, and various vlan's and connections on the 1GB RJ45's with no problems.
However, we have a number of 10Gbps BaseT connections te3/1 - te3/5 which are causing us issues. On a reload of the switch or removal / re-install of the cable it can take anywhere up to an hour for the port to become active again. So when we reload the switch, we may get a connection come up after say 3 mins, but the port next to it may not come up for 15-60 min. The cabling is all the same (CAT6 and has been tested/verified) and all connections go to Broadcom 10Gb cards in Dell 820 servers running vmware. We have the following set on the ports:
switchport mode access
spanning-tree portfast
No speed or duplex can be set on these ports - these options are not available in the config.
Once a link is finally established, it will hold the link solid with no problems, but this is a problem for us, we can't have a reboot take an undetermined amount of time for the link to come back.
Cisco Switching/Routing :: Catalyst 3750-x Icmp Delay To Default Gateway?

Mar 31, 2012I 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.

Dec 12, 2011I 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.

View 25 Replies View RelatedCisco :: Serialization Delay From The Wire / Interface Onto Router / Switch Backplane / Fabric?
Feb 28, 2013So the delay is introduced getting data onto the wire. However say there are two hops to the destination server, each hop is via equal connectivity speeds say 1G interlinks.
Question:
Is there serialization delay FROM the wire/interface onto router/switch backplane/fabric?
Is the serialization delay from backplace/nic back onto the wire to the next hop? - Or if using a switch with equal in/output speed transmitted without serialization?
What happens with a routed interface vs switched?
Most articles discuss the latency induced between the much higher OS/NIC interface out to the wire, but not the switch/router serialization that does or doesn't occur.

View 6 Replies View RelatedCisco LAN :: 3560 Cannot Ping After Moving PC From Switch To Switch
Apr 15, 2013I have a 2 cisco switches that are at different sites one is a Cisco CAT4500 and other 3560. The connection between the switches is a layer 2 fibre link. CAT4500 and 3560 both have VLAN interface ip addresses in order for me to connect to the switches.
I have PC A connected to CAT4500 and PC B connecting to 3560. All these devices are the same VLAN and in the same subnet. I do have trunk links all the way though allowing this vlan as we run vlans. From PC A, I can ping CAT4500, 3560 and even PC B. This tells me everything is fine regarding Layer 2 & 3.
As soon as I move PC B and connect it to the other switch CAT4500 or move the other PC vice versa (this happens in both directions). Both switches learn that the mac address has moved locations and updates its mac address table accordingly. So when I do a show mac address table and show arp, everything has learned and moved fine. However when I try to ping any other device from PC B I cannot. So the 3560 switch PC B was originally connected to, I can no longer ping, the switch cannot see the pc also. It is as if PC B has not learned anything from the switch and cannot respond or reply to any icmp. I have tried this with different end devices, same thing. I am now thinking it has something to do with the switch.
