I have a GLBP config consisting of two Cat4506e switches, connecting over 10G fiber to Cat3560E switches. Testing, I have a laptop connected to one of the 3560 switches with a constant ping to the Virtual IP addresses of the GLBP on two different VLANs, and the switches themselves. Both 4500s are configured the same (as seen below). When I reload the .252 switch, I do not lose a packet, but when I reload the .253 switch, I lose about 6 seconds of ICMP. It looks like when the 10G interface comes up, it puts all switchports in a blocking mode. I checked the int. when testing, but it shows it as up/up. Any ideas?
