I am running ASR1004's for NAT only. I want to use both dynamic NAT and PAT. Actually, what I want is a dynamic NAT pool of say 1000 or so addresses that will fall over to a PAT range if the address space in the dynamic NAT translations are exhaust...
I recently performed an NX-OS upgrade on a pair of 5596's running in vPC mode. Due to some lingering spanning-tree in the datacenter, this was a non-ISSU upgrade. We upgraded one switch at a time using the "install all..." command, with the idea th...
I have a dual-homed fabric (Nexus 2248 dual attached to two Nexus 5020's via vPC). On this Nexus 2248 is a server that has a four port LACP etherchannel. The ports do not appear to be load balancing correctly. The output below shows the four ports...
We manage a campus MPLS network comprised of Cisco 76xx routers as my "P" devices. Attached to the MPLS core are several PE devices (Cisco 6509 VSS pairs). I have a single VRF named "students" that exists across all my PE devices. Across this "stu...
I built a VSS pair with a couple of 6509's. This was our first pair so we took the opportunity to do some testing. One of the features we tested was the priority/preemption feature, which we decided not to use. After some time we shutdown switch 1...
Thanks for the reply Edwin. To answer your question we are a university and have approx 45,000 users. Just on the wireless network alone we had over 100,000 devices registered last year (phones, laptops, ipads, etc). We peak at around 30,000 simult...
Hi,A quick question about port-channel load balancing algorithms on a Nexus 5020. Can I change the algorithm on the fly without adverse affects? I need to change from "source dest IP" to "source dest port" but I am worried about what happens to my ...
So a little more information...Got more details from the server folks yesterday. The stats I posted above are not a true representation as the port-channel was mostly idle at that time. When it is active the server guys see outbound traffic from th...
Unfortunately NAT is not an option on our Edge-PE devices. Corp policy dictates the use of the firewalls for NAT in this case. Besides, we really do not wish to perform NAT on our PE devices.
