Can a port be part of a port share and then the port share be part of an MLAG?


Can a port share then be added to an MLAG? Client wants to have Layer 2 or Layer 3 sharing capabilities and then do a MLAG using those ports or the sharing ports. Is there some way to do this? Currently they have a Stack and are sharing between the Stack. They want to break the stack so as to be able to perform a firmware upgrade without taking everything down. In order to do this they want the sharing for the ports that are going to their virtual environment as well as be able then to MLAG them together between the switches.

We just moved our core from Cisco to Extreme last month, so I am still a newbie but I can tell you that yes we are doing load sharing and mlags on key servers/equipment connected to our two Extreme X690 cores.

Here is a snippit of some of our ports. I think it has to be applied in a certain order, I forget but anyway if it doesn't take the sharing command after its an mlag, then undo the mlag and do the sharing command and then do the mlag.... basically you can figure it out.

Same on both switches:
enable sharing 1:1 grouping 1:1 algorithm address-based L3_L4 lacp
enable sharing 1:2 grouping 1:2 algorithm address-based L3_L4 lacp
enable sharing 1:3 grouping 1:3 algorithm address-based L3_L4 lacp
enable sharing 2:7 grouping 2:7-8 algorithm address-based L3_L4 lacp
enable sharing 2:29 grouping 2:29 algorithm address-based L3_L4 lacp
enable sharing 2:30 grouping 2:30 algorithm address-based L3_L4 lacp
enable sharing 2:6 grouping 2:6 algorithm address-based L3_L4 lacp
enable sharing 2:1 grouping 2:1-2 algorithm address-based L2
enable sharing 2:48 grouping 2:48 algorithm address-based L3_L4 lacp
enable sharing 2:9 grouping 2:9 algorithm address-based L3_L4 lacp

On our one X690 stack (we call yellow since its all yellow cables connected to it)
create mlag peer "PURPLE"
configure mlag peer "PURPLE" ipaddress 1.2.1.1 vr VR-Default
enable mlag port 1:1 peer "PURPLE" id 101
enable mlag port 1:2 peer "PURPLE" id 102
enable mlag port 1:3 peer "PURPLE" id 103
enable mlag port 2:1 peer "PURPLE" id 201
enable mlag port 2:6 peer "PURPLE" id 206
enable mlag port 2:7 peer "PURPLE" id 207
enable mlag port 2:9 peer "PURPLE" id 209
enable mlag port 2:29 peer "PURPLE" id 229
enable mlag port 2:30 peer "PURPLE" id 230
enable mlag port 2:48 peer "PURPLE" id 248

On our other X690 stack (we call purple since its all purple cables connected to it)
create mlag peer "YELLOW"
configure mlag peer "YELLOW" ipaddress 1.2.1.2 vr VR-Default
enable mlag port 1:1 peer "YELLOW" id 101
enable mlag port 1:2 peer "YELLOW" id 102
enable mlag port 1:3 peer "YELLOW" id 103
enable mlag port 2:1 peer "YELLOW" id 201
enable mlag port 2:6 peer "YELLOW" id 206
enable mlag port 2:7 peer "YELLOW" id 207
enable mlag port 2:9 peer "YELLOW" id 209
enable mlag port 2:29 peer "YELLOW" id 229
enable mlag port 2:30 peer "YELLOW" id 230
enable mlag port 2:48 peer "YELLOW" id 248
