I'm trying to deploy 1000v in a lab and I'm having trouble adding an ESXi host to the 1000v switch. I'm using VSUM 2.0 wizard to add the ESXi host to the 1000v. The vSphere Tasks shows the following line:
Name: Add host to Cisco DVS, Status: fault.co...
I recently noticed intermittent latency when pinging my ASA's interfaces. I see the same latency when pinging hosts through the ASA.For instance, when I ping the ASA's interface on my local network, 172.16.0.1, I normally see 1ms RTT, but every once ...
We recently extended our access layer using a pair of 5ks with extenders. We have a pair of 6509s at our core and they handle the intra-VLAN routing with SVIs. I recently noticed that access hosts connected to the extenders cannot pass traffic betwee...
A while back I changed my internal interface ACLs so we must explictly permit traffic between internal networks but still retain access to the internet. I chose to use an object group containing the three RFC1918 ranges to define the private networks...
We have a 2960S using a single SFP-10GBase-SR to our Core switch. We are planning connecting the 2960S to a pair of Nexus 5k switches using Copper SFPs. We are already doing this on another 2960S so I didn't expect any surprises.When I removed the un...
Thanks for the suggestions. I ran a capture on the firewall it does not reflect the high response times I'm seeing in my ping output. I checked the switchport interfaces where the packets travel across and didn't see any interface errors. I think I m...
I don't know why it would take 10 to 15 minutes for TCP applications to recover. Do new connections pass through the firewall? Maybe you have some ARP caching or possibly switch port security is causing delays learning the new MAC address of the seco...
The ASA is a stateful firewall so it tracks all the connections. When you boot up the backup ASA there is nothing in its connection table. It will drop all the traffic from those previous connections because it did not see the initial TCP handshake. ...
