Hi All,We have two buildings A and B next to each other running 10gb fiber (ATT) between them. Building A CAT 3560 connects to building B CAT 3570 over this fiber cable. Building A has a T3 to internet for data and voice. There is a firewall with 3 i...
This should be easy, but I'm having problems.I have a pair of layer 3 switches which are talking OSPF. On each switch there are a few static routes which I want to advertise to the other switch. I've redistributed these into OSPF for this purpose. Ho...
Hi,We have mutiple 6509 switches with VS-S720-10G. When we reboot the switch manually it goes to rommon sometimes. We found that SP registry value was changed to some wrong value (0x0 i remember) automatically. Then we corrected to 0x2102 manually by...
