C9600-LC-24C Description

The C9600-LC-24C is a Cisco Catalyst 9600 Series single-slot QSFP28 line card for medium port-density campus core designs. The card provides 24 ports at 40 GE or 12 ports at 100 GE with C9600-SUP-1, and 24 ports of 100/40 GE with C9600X-SUP-2, in the Catalyst 9606R chassis. MACsec-256 runs with C9600-SUP-1, but the card does not support MACsec with C9600X-SUP-2.

Application Scenarios

Medium-Density Campus Core

In a campus core where a moderate number of fast trunks matters more than wide fan-out, the line card fills a Catalyst 9606R slot with 40 GE and 100 GE QSFP28 ports.

Inter-Building Backbone

Where 40 GE or 100 GE links between buildings converge on one modular chassis, the card terminates them on QSFP28 ports at line rate.

C9600-LC-24C is the QSFP28 card of this group, with 24 ports at 40 GE and 100 GE, while C9600-LC-48YL carries 48 SFP56 ports at up to 50 GE, so the choice starts with whether the links are fewer and faster or many and moderate. Both cards run on C9600-SUP-1 and C9600X-SUP-2, and neither supports MACsec with C9600X-SUP-2; a chassis that needs MACsec on that engine together with 100G ports needs C9600X-LC-32CD. Links above 100 GE, such as 400 GE, also need C9600X-LC-32CD, which runs only with C9600X-SUP-2 and holds 128 100G ports in a C9606R against 96 here. A C9606R on C9600-SUP-1 stays with C9600-LC-24C, since C9600X-LC-32CD is not supported on that engine.

Ordering Checklist

  • Chassis: Install the card in the Catalyst 9600 Series 6 Slot Chassis, PID C9606R, the only chassis listed for this line card. It has 4 line card slots, and slots 3 and 4 are reserved for supervisor engines.
  • Supervisor engines: Pair the card with C9600-SUP-1 or C9600X-SUP-2, since both engines support it.

Questions & Answers

  • Which chassis does C9600-LC-24C install in?

    C9600-LC-24C installs in the Catalyst 9606R, the only chassis listed for the card. The 6-slot chassis has 4 line card slots, because slots 3 and 4 are reserved for the two supervisor engines.
  • Which software release does C9600-LC-24C require?

    C9600-LC-24C requires Cisco IOS XE 16.11.1 with C9600-SUP-1 and Cisco IOS XE 17.7.1 with C9600X-SUP-2. The minimum software release therefore depends on which supervisor engine is installed in the Catalyst 9606R chassis.
  • Why does C9600-LC-24C show only 12 ports at 100 GE with C9600-SUP-1?

    With C9600-SUP-1 the ports work in pairs. The odd port runs 100 GE and the next even port is disabled, which gives at most 12 ports at 100 GE, and 24 ports at 40 GE is the default. With C9600X-SUP-2 no pairing applies, and all 24 ports run at 100 GE.
  • How are the ports of C9600-LC-24C numbered when 100 GE ports are paired?

    With C9600-SUP-1 the interfaces show ports 1 to 24 as 40 GE and ports 25 to 48 as 100 GE, and each 100 GE odd port disables the next even port. With C9600X-SUP-2 a single numbering of 1 to 24 covers both 100 GE and 40 GE. This follows the port mapping in the Catalyst 9600 interface configuration guide.
  • How many 40 GE ports can a C9606R reach with C9600-LC-24C cards?

    A C9606R reaches 96 ports at 40 GE with C9600-LC-24C cards on either C9600-SUP-1 or C9600X-SUP-2. At 100 GE the same cards reach 48 ports with C9600-SUP-1 and 96 ports with C9600X-SUP-2. A CVR adapter on each port gives 96 ports at 10 GE.
  • Why does C9600-LC-24C lose MACsec when it runs with C9600X-SUP-2?

    C9600-LC-24C is a Gen 1 line card that holds only PHYs, and all forwarding happens on the supervisor. C9600X-SUP-2 uses a Q200 ASIC that has no crypto engine, and the Gen 1 CDR4 PHYs are not MACsec capable. MACsec-256 on this card therefore needs C9600-SUP-1.
  • Which other line cards can run beside C9600-LC-24C with each supervisor?

    With C9600-SUP-1 the chassis can also hold C9600-LC-48YL, C9600-LC-48TX, C9600-LC-48S and C9600-LC-40YL4CD. With C9600X-SUP-2 it can hold C9600-LC-48YL, C9600-LC-48TX, C9600-LC-40YL4CD, C9600X-LC-32CD and C9600X-LC-56YL4C. C9600-LC-48S is not supported with C9600X-SUP-2.
