Q. What is the Purpose of Access-List Entry (ACE) Counter?
A. The ACE counter is used in order to maintain the Access-List (ACL) statistics.
Q. Is a 40-Gb module supported on a Supervisor Engine 2T (SUP2T), and what is the model number of the line card if it is?
A. A. Yes. A 40-Gb module is supported on SUP2T, and the model number of the line card is WS-X6904-40G-2T. For more information about this, reference the Cisco article below.
Q. Are platform hardware rate-limiters enabled by default?
A. Some rate-limiters are enabled by default, but not all. Enter the show platform rate-limit command in order to view the list of rate-limiters.
Q. When the master stack member resets, does the uplink ether channel reset or failover?
A. Failover occurs quickly, and there is no network outage, even if the master stack member uplink ether channel goes down.
6800IA (Instant Access) and FEX related Questions
Q. Is there a release date for instant access that includes more than 21FEX, and does it require a new SUP or software update?
A. Support for 2000 access ports is targeted in Release 15.2(1)SY, which has an anticipated release date of December 2014. This is still in the testing phase, and details will be available in April 2014. The goal is to support 2000 ports with both SUP2T and 6880-X.
Q. What are the differences between the 6500IA and Normal 6500?
Q. What is the maximum number of three-switch stacks that can be added to the CAT6K Series switch?
A. You can add up to seven nodes, and each node carries three 6848 IA stack members.
Q. Is trust dscp/cos supported in IA Clients?
A. Only trust DSCP is currently supported by the ports.
Q. What is the maximum number of queues supported on the 6848IA?
A. There are four queues in the 6848 platform: one is a priority queue, and the others are standard queues. The priority queue only carries control plain traffic, such as <expand this acronym> (BPDU). All of the standard queues are used for normal traffic.
Q. Is the In-Service Software Upgrade (ISSU) feature supported on a CA T6K Series Switch with a 6848IA client?
A. Yes. The ISSU feature is supported on a 6848IA client and we can used during an IOS upgrade.
Q. If there are two uplinks from the FEX to the CAT 6K, does the spanning tree block one of the ports?
A. No. The uplink port will not be block and it is always in the forwarded state.
