SMC's TigerSwitch 6752AL2

This new workgroup switch is port-rich and dirt cheap, but it's not perfect.

Stalking a TigerSwitch

In our Syracuse University Real-World Labs®, I pointed InterWorking Labs' SilverCreek Pro SP Edition 9.0.5 at the switch to test the latter's MIB compliance with SNMP 1 and 2c. Under version 1, it passed 37 of 45 tests; under version 2c, it passed 72 of 80 tests. If you have an SNMP or RMON management environment, the TigerSwitch will fit but provide a less-than-perfect picture of your network's health, so thoroughly test the TigerSwitch before you rely on it.

I attached Spirent's SMB-600B chassis (version 2.60) with a LAN-3325A Dual Media Ethernet Terametrics XD (four-port Gigabit Ethernet) card to the TigerSwitch. Using Spirent's SmartFlow (version 4.50.087), I dedicated two of the four ports to passing Layer 2 100Base-TX traffic through the TigerSwitch and wedded the other two ports to passing Layer 2 1000Base-TX traffic through the switch. The throughput tests started out slowly, utilizing 10 percent of available bandwidth. Every 30 seconds, bandwidth use increased by increments of 10 percent until it peaked at 100 percent.

The 10/100Base-TX ports and the 1000Base-TX ports had a difficult time initializing ports for end nodes. In the first 30 seconds of testing, using only 10 percent of available bandwidth per port, the TigerSwitch dropped about 65 percent of the frames passing through both the 100Base-TX and the 1000Base-TX ports.
