From 52b37fa5f1096b60447bc8a9ebb2310d7f551af6 Mon Sep 17 00:00:00 2001 From: Shaun Ruffell Date: Tue, 5 Jul 2011 20:13:49 +0000 Subject: [PATCH] system.conf.sample: Add note regarding cross connecting spans on B410P. There is an issue with the hardware on the B410P that makes it unreliable to connect one of the ports to another port for testing.
