I need to implement ISR-WAAS on this ISR 4400 router. From the "show virtual-service" below, does it mean the router has 4 GB memory, 1G Flash, and about 200 GB storage volume? If that's the case, I need to plan for memory upgrade to 8 GB at least? ISR-router# show virtual-service Virtual Service Global State and Virtualization Limits: Infrastructure version : 1.6 Total virtual services installed : 0 Total virtual services activated : 0 Machine types supported   : KVM, LXC Machine types disabled    : none Maximum VCPUs per virtual service : 4 Resource virtualization limits: Name                              Quota     Committed     Available  -------------------------------------------------------------- system CPU (%)                  75             0            75  memory (MB)                   4096             0           4096  bootflash (MB)                 1000             0           1000  harddisk (MB)                20000             0           19134  volume-group (MB)      190768             0           170288    I also did a "dir all" on the router, but didn't see "ISR-WAAS OVA" file on bootflash: or harddisk: So I need to copy the OVA file to the router first. Correct?   Thanks ... View more

I'm new to WAAS 5.5.1. I have created a few new application policies in Central Manager, however I couldn't tell if the new policies are on top of the existing default policies. In Central Manager application policy page, it only listed the new policies. Can I assume all the WAAS default policies are still being used by default?   Years ago in old version 4, Central Manager would list new policies and also all the default policies. I was expecting still seeing the same in newer software releases.   And another question: where in Central Manager can you see the default policies?   Thanks Gary ... View more

I'm using a 3750 switch for 4500 VSS dual active detection using enhanced PAgP. I like to monitor and log how the active switch detects dual active and recover. Are there "show" or "debug" commands to use for this purpose? Thanks in advance ... View more

I have a 3750 stack switch I can connect to a 4500X VSS pair for dual-active detection. How can I check if the 3750 supports enhanced PAgP? Thanks ... View more

I have a pair of Nexus 56128 configured with fabric path and vpc+. The Nexus pair has UCS connected downstream using vpc port-channels. When a Vlan is in mode fabricpath, it's ok for the vpc+ peer-link and the vpc port-channel to UCS. However when I changed the vlan to classic Ethernet, it's err-diabled in the vpc port-channels. Is this the normal behavior of fabric path domain? In other words, CE Vlans and fabric path Vlans cannot use the same Layer 2 path, correct? If I need to transport CE Vlans and fabric path Vlans from Nexus (fabric path vpc+) to UCS, I have to use a separate non-vpc port-channel for the CE Vlans between each Nexus and UCS? Thanks ...

I'll use a pair of Nexus 56128 for SAN switching between VM hosts and EMC storage. To enable "feature npiv", do I need to enable "feature fcoe" first? I seem to remember that was the case a few years ago. With this Nexus SAN, all SAN connections are native fiber channel, no FCoE. Thanks ... View more

In our new data center, there's a pair of Nexus 5600 functioning as L2/L3 distribution. We plan to configure the Nexus pair with fabric path so in the future when access Nexus switches are added, the 5600 pair can function as fabric path spines. Right now there are no other fabric path access switches connected. In this special case, would fabric path have negative affects to normal Layer 2 functions of the 5600 pair? Thanks ... View more

We are building a new data center where 4500 VSS will function as the core, and a pair of Nexus 56128 function as L2/L3 distribution. Between the core and pair of 56128, it's Layer 3 connections in a triangle topology (no vpc). During migration, some Vlans need to be trunked between the core and the 56128 pair. With the triangle topology without using vpc, from spanning-tree perspective, will one leg of the triangle (core --- one of the 56128) in spanning-tree blocking state? Thanks ... View more
