Hi guys, I just added a stack two Cisco 3750G to a stack 4 Cisco 3750 (All SFPs) via trunk and port-channel. Po6   configuration seems to be correct as I have 7 other stacks connected in same manner.   at the core side all links are Solid Amber. sh int 1/0/6 through 4/0/6 are solid Amber. up links at the stack of two Cisco 3750G are Green.   at the core side, sh int gi1/0/6 - 4/0/6 are up line protocol down (suspended). seems like Spanning tree but show commands do not show any indication if blocking!?   any help/suggestions would be greatly appreciated folks. have checked:   VTP ver 3, domain, mode, pass at both sides found no issues.   core is primary VTP master and all nodes are transparent mode Best Regards,   Best Regards,   Masood   Masood   ...

HI folks,   I have 8 stand alone Cisco 3750G-PS-S Switches. I have upgraded 7 out of 8 Switches with IP Sevices successfully but one gives me hard time. its timing out.   1- there is communication between the switch and the TFTP server (laptop connected to switchport - same subnet through a vlan). 2- ping between both devices successful. 3- forced del current ip base like I did on others to have enough space. 4- tested writing to flash - passed. 5-formatted Flash and wrote to it running config and vlan .dat 6-added exec-timeout 0 0 to con 0   Still have the same error. is there something that I am missing. I am using .bin IOS file as I did on other 7 switches.   Please advise,   Best Regards,   Masood     ... View more
