In an all-Cisco MST environment, will "spanning-tree mst forward-time XXX" affect the speed of the fast switch-to-switch handshake? Or only affect edge ports (how many seconds to wait, when there is no fast handshake)? I'd like to slow-down the han...

Let's say that UCS System QoS has Enabled Priorities:- Platinum, CS5, 30%, no-drop- Bronze, CS2, 20%- Best Effort, Any, N/A% If a UCS QoS Policy called "MostlyBronze" is configured with "Priority: Bronze" and "Host Control: None", then all traffic re...

When connecting to an ASA with self-signed cert, using Cisco AnyConnect Secure Mobility Client 3.1 (10010), the AnyConnect client presents the Big Red Box of Warning, which is good. The user would need to disable "Block Connections to Unknown Server...

I'm placing a c3560x in-front of a firewall (between the firewall and Internet) in order to discard DoS attack traffic at wire-speed. Traffic which is possibly DoS attack traffic, is arriving at my catalyst already marked with CoS 2 by another devi...

On 3560x, I'd like to markdown any traffic received >100mbps to CS2. It looks like the only markdown map available is DSCP-based, not CoS-based (there is no "police ... exceed-action policed-cos-transmit" command)Does that mean I need to:-not trust D...

Hi, Peter. This regards a customer's MST network, operating in a ring topology. Each ring segment iscarried over a metroE point-to-point segment, but without link propagation. One segment of this network was mostly down, but working intermittently...

Thanks. It sounds like the operation is basically equivalent to old catalyst "trust cos" or "set cos X".Web design: If the "Priority:" drop-down does nothing, whenever HostControl:Full is clicked, then the dialog is misleading. Either "HostControl:...

Thanks, Justin. Does that mean that the Priority drop-down does absolutely nothing, if HostControl:Full is clicked? Whether the Priority is set to Platinum or Bronze would not matter, because CoS is trusted? Or, perhaps does the Priority drop-down ...

Vielen dank/merci vielmal, Markus. It does sound like a CS1 scavenger use-case. One concern I have is with false-positives, and wasted buffers: in my use-case there are actually many firewalls, one on each switchport. If a different firewall is u...

Thanks, Julio. I would like to filter, in order to reduce the amount of data captured by a packet-capture. Not for security purposes.For example, when debugging a problem, sometimes it helps to view all flows through an interface; but you don't wan...
