I'm super new to Nexus, so I'm not really sure how to troubleshoot this. I did a quick search and found that this is related to DCBX TLVs in LLDP, which we apparently shouldn't be getting on a regular ethernet port. I'm pretty sure this is just a reg...
I'm running the latest v5 of the client on Vista 64-bit. It's been working for weeks and suddenly quit working. I don't see any errors in the logs. The only thing I notice in the statistics is that there are zero packets decrypted or encrypted. I'm a...
We have an ASA and need to find a way to disable ARP security on the inside interface. We are going to put a device in front of it that is a sort of nearly-transparent proxy, but it unfortunately rewrites packets that travel through it with its own M...
I'm only lightly familiar with the ASA, so I don't know if this is even possible. Here's what we'd like to do:We have some mobile laptops with Sprint cards as well as wifi cards. These laptops would have a Cisco VPN client installed. We want them to ...
This is a weird one and it's happened twice in the past couple of months. We have port security active on our switches and twice we've seen it get tripped by an invalid MAC address like e8be.5bd3.5558. It's as if the machines that are connected to it...
Thanks! That's very helpful information. I'll have the server owners check into that setting. I suspect we'll probably just disable LLDP since we don't really need it on any of these interfaces.I appreciate the help!
Isn't a CNA for FC or FCoE? Can they do regular Ethernet, too? I thought that a CNA was only for FC or FCoE. I verified that we're not doing FC or FCoE on these Nexus switches. I'll have the server owners check into it.Thanks!
Well, i guess for the sake of posterity and anyone who stumbles across this, it was ZoneAlarm. It was blocking it but not logging that it was blocking it. I uninstalled ZA and now my VPN client works just fine.
I'm starting to think it's my software firewall. I just installed it a few days ago. I'm wondering now if there is an incompatibility with ZA and the Cisco VPN Client. I'll uninstall it tonight and see if that fixes the problem.
No, that wouldn't work. I'd have to create a static ARP entry for every device requiring internet access.I'm beginning to think this isn't the problem, anyway. It doesn't look to me like we have any sort of ARP spoofing protection turned on.
