We've got an 7600-ES20-GE3CXL HW 1.2 FW 12.2(33r)SRB SW 12.2(33)SRC4 in a 7609/Sup720 3BXL chassis. We ran some performance tests for a customer, and we were quite appalled by the results. We're using Exfo test sets to run RFC2544 patterns between two ports.
We're using 7 frame sizes; 64, 128, 256, 512, 1024, 1280, 1518. When we look at the throughput results, we see this: Frame Size TX-to-RX - Layer 1-2-3 (Mbps) 64 449.197861 128 538.181818 256 560.97561 512 974.358974 1024 956.043956 1280 1000 1518 994.825356 Now if we do that same test on another card, say a WS-X6724-SFP, we get very different results: Frame Size TX-to-RX - Layer 1-2-3 (Mbps) 64 1000 128 1000 256 1000 512 1000 1024 1000 1280 1000 1518 1000 I've tried the same test on a Juniper EX4200, and an ME3400E-12CS and all the results are identical to the WS-X6724-SFP. The ES20 seems to be the anomaly here. I know that processing smaller packets is generally much more taxing than processing large packets, so I didn't really expect to see line rate on any of the tests that were run, but considering the 6724 reported what seem to be line rate results vs. the ES20, I can't help but to wonder whether I've got a bad card or something. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
