I was attempting to troubleshoot a logon problem with some machines, when it was finally revealed that there was a managed switch between the host and the target preventing this.
How would I detect this in the future? (A tracert showed nothing between host and target.) Would Wireshark show me this info, with reduced TTLs?
getting a picture of all devices between a host and a target?
I'm the sole IT worker at this company and I specialize in everything but big, corporate networking so here's a dumb question. How do I determine the IP address of one of our two switches? I need a list of MAC addresses of connected devices so I can relabel all the cables that were mislabeled (and this is a managed switch). For the other switch, which was put in by someone who knew what they were doing, you just type ss3900 into a browser and tada, 3com Superstack 3900 login so apparently someone did some fancy DNS stuff or whatever.
For this HP Procurve, the idiot before me who got fired for completely screwing up everything didn't leave any documentation or labeling and didn't use the same IP address as the Cisco switch that was pulled out. Obviously the switch is invisible to my PC from an IP standpoint
How to determine why my HP Pro-curve switch randomly faults and resets during the day, about 3 to 5 times?

View 3 Replies View RelatedWeb auth redirect URL gets dropped if stateful firewall is between webauth host and switch management interface. Aaron at Cisco live london kinda hinted about maybe Cisco working on this ? We can't disable stateful inspection. Is there any other solutions or workarounds ?
"Although this approach introduces additional hops in the return path from the switch to the host, it produces negligible load on the default router and intervening infrastructure since only the WebAuth traffic from the switch to the host follows this path. In campus designs that do not use SVIs on the data VLAN,6 a default route is typically already configured. In this case, no additional configuration is required to support WebAuth.
However, problems may arise in the case in which traffic to the default router is bridged through a stateful firewall. The original SYN packet in the TCP handshake is consumed by the access switch, so the first packet that the firewall sees is the SYN-ACK packet from the access switch. Stateful firewalls typically drop SYN-ACK packets if they have not seen the original SYN packet.In this case, you will need to turn off stateful inspection for ports 80 and 443 on the firewall."

View 1 Replies View RelatedMy company recently purchased a custom domain name through In Motion Hosting (inmotionhosting.com) which has worked great up until today. As of this morning we are not able to view our webpage online (ronnysinc.com) or any inmotionhosting pages including our email accounts. However, we can view any other website and computers outside of our network seem to be able to view those pages without any problem. [code] As you can see it works fine with any other website such as google.

I also tried resetting the router and flushing the DNS with no success.

Today when we run one applcation to access a target server with IP address 10.2.2.13, the application cannot run through and appearing error message related networking.The target server has two network ports whereby another one with IP 10.2.2.14 is running OK with the same application. All these two connections are connected to the same Cisco switch 3750, after the switch then go to Cisco ASA firewall which has no access control rule for this 10.2.2.13 and its subnet, and then the firewall connect directly to the application server.We can ping, remote desktop access and telent port for the application to the target server by using 10.2.2.13.We swapped the cable connection of the ports from one another and try the application again, the IP with 10.2.2.13 is still fail and IP with 10.2.2.14 is OK.We then change the IP from 10.2.2.13 to 10.2.2.12 or 10.2.2.155, all are OK. We changed back to 10.2.2.13, it is failed again.The switch is in running real time production and so we cannot power cycle or reload the switch.

This is working well except for the fact that if a target device is in ROMMON mode, the console server refuses to displays the target device console. It does open the connection but the ROMMON prompt is not shown on the console server . This is essential for this device as we will need to use it to reset passwords remotely and thus need to be able to access ROMMON mode from the console server.

View 2 Replies View RelatedI have and 880 W router. The LAN members can get out t o the internet. Now I want to configure NAT such that outside computers can access a couple of the machines using Remote Desktop (RDP). I am using Configuration Professional.
When I configure inside to outside, the remote computers can't connect to the target machines.When I configure outside to inside, the target machines acn't get to the internet.
When I try to use the advanced NAT definition wizard, I can't complete the task because the only inside pool (?) or LAN (?) is "designated" and not available to select. I can't free it up without deleting the one working NAT entry which is the one that enables all computers to reach the internet.
I have a site with a 1700 router connected to a 2960 switch. For some of the computers on site I want to determine how much traffic is local to the LAN and how much is going across the WAN.
One strategy I've come up with is to reset the interface counters on the switch ports to the machines in question and after some time compare the total bytes in and out of the interface with netflow data from the router. My only concern is that netflow is not completely accurate about the amount of data that has passed through an interface.
Is there a better or more accurate way to accomplish my goal?
