We evaluated the Cisco Catalyst 4500 with functionality, performance and energy efficiency tests on the Ethernet. The Spirent TestCenter-used the efficiency checks. Instrument for testing layer-2 unicast output and latency; layer-3 efficiency and latency, including independent IPv4 and IPv6 tests; layer-2 multicast and latency; Learn more on WS-C3750X-24T-S.
Layer-2 MAC address capability; and program updates and downgrades (ISSU / ISSD) in operation. All tests used in Cisco’s IOS-XE software version 03.02.00.2.70 (with a .80
ISSU test release) and Spirent TestCenter Software version 3.62.
The Sifos PowerSync analyzer received a cumulative power of 60 watts at each of 24 switch ports inside a single module during all output checks. Switch was not affected
Power draw throughput or latency, as demonstrated by virtually identical performance over Ethernet for streams on ports with and without power.
We assessed UPoE functionality in two ways : firstly, by using the Sifos analyzer to draw 60 watts on 24 switch ports simultaneously, and secondly, by attaching different devices to it
Switching. These products included a Cisco 9971 phone with a thin-client computer; a 23-inch display from Samsung SyncMaster NC220; and a turret from BT ITS.Netrix.
The efficiency evaluations of unicast included a completely meshed traffic pattern between 384 gigabit Ethernet switch ports. The generator / analyser from the Spirent TestCenter delivered traffic for a
Duration 60 seconds, and latency measurement for each frame received.
We replicated this check with Ethernet frames of 64-, 256-, 1,518-, and 9,216 bytes (and removed 78
-Byte frames for 64-byte frames in the test case IPv6, as this is the shortest possible duration that can match the test instrument ‘s signature field).
A network configuration of one transmitter port and 383 receiver (subscriber) ports was used in the multicast network check. Here, all 383 Spirent TestCenter receiver ports
Instrument used IGMPv3 has joined the same 1,000 multicast groups. After the IGMP snooping table of the switch was fully filled in, the test instrument then offered traffic to the switch
Single transmit channel, with all 1,000 multicast party destination addresses. The instrument, as in the unicast tests, measured throughput and latency over four frame lengths.
