Extreme Networks Multi-switch Link Aggregation Group

Extreme 終於在 XOS 12.5.1 有了 Nortel 大概至少五年前就擁有的技術 (SMLT Split Multi-Link Trunking)也就是跨 Physical Switch 的 Link Aggregation。

Support Hardware

BlackDiamond 8800 switches
Summit XOS Series
Same Platform Family request

Note

總覺得這功能大概是 EAPS 改來的吧，一樣要在二台 switch 之間要有直接連線並使用一個 Control vlan 來進行溝通，再將傳輸 data 的 vlan 加進這個連線中

Config Example

X350-24t-01.txt

create vlan "vMLAG_ISC"
configure vlan vMLAG_ISC tag 3999
enable sharing 19 grouping 19-20 algorithm address-based L2
configure vlan vMLAG_ISC add ports 19 tagged
configure vlan vMLAG_ISC ipaddress 192.168.255.1 255.255.255.252
create mlag peer "X350-24t-02"
