Hi, We are planning to upgrade a centrel Nexus 7k DC VPC installation. Today: Redundant SUP-1 M1-32XP linecards Fab-1 fabric moules (3) Two nodes in VPC configuration with NxOS 5.2 New: Redundant SUP-2E F3-48XP linecards Fab-2 fabric modules (5) NxOS 7.2 The rough plan is to: Bring down (shut off power) on VPC secondary node Check that traffic flows via primary Change Fabric modules, Supervisors (with NxOS 7.2 and config prepared) and linecards Connect all cables Bring up the upgraded node Now we're half way with a VPC pair comprising different HW and SW. See below ... Does this work? Can we get any strange problems here? Then: Bring down the other node Check that traffic flows via the new upgraded node Change Fabric modules, Supervisors and linecards Connect all cables Bring up the upgraded node Test! /Jorgen ...

Hi, We are about to start a project that shall secure an organisations wired network. This organisation has 40k clients and around 250k network attached devices (clients, printers, cams, medical equipment, environmental equipment ...) There are about 3000 Cisco switches connecting the  clients. 802.1x  and Cisco ISE are used for the wireless network (10k clients). Is Cisco ISE the way to go for the wired network as well? Does it scale? Things to think about when designing the solution? /Jorgen ... View more

Hi, I read the following in a Cisco Live presentation about the 4 10G ports on a 9000v satellite: "Initially used as Fabric Ports ONLY (could be used as access port in the future)" I wonder - which release represents "the future"? 5.1.1? /Jorgen ... View more

We have a DC network comprising 2 x VSS clusters and 2 x Nexus 5020 VPC pairs. The 5020 switches do not have "peer-switch" defined (i.e is seen as individual STP bridges). To simplify and to make the solution more robust we are planning to configure "peer-switch" on all Nexus 5000 switches. What kind of downtime can we calculate with when configuring this? What actually happens when "peer-switch" is defined? See attached drawing. NxOS version 5.2.1.N1.6 /Jorgen ... View more

Hi, We are in progress rolling out a couple of ASR901 as WAN CPE routers. We are planning to use HQF (Hierachical QoS Framework). Have a pretty basic parent - child config (see below). When I apply the policy on the WAN facing interface nothing actually happens. The policy is not applied and I do not get any error message. Tried same polilcy on other router platforms, and it works OK there.

When I boot one of the switches in a VPC pair the following happens: - the other switch is taking over the vpc primary role (if booting primary) - the switch boots up - when the switch is up again I get 10 - 20s of total outage for the traffic through the VPC pair. In a Datacenter tjis is not acceptable. Why do I get this outage? Sw ver 5.2 Sent from Cisco Technical Support iPad App ... View more
