====== 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 =====
<code config XOS-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

configure mlag ports convergence-control fast
create mlag peer "X350-24t-02"
configure mlag peer "X350-24t-02" ipaddress 192.168.255.2
enable mlag port 1 peer "X350-24t-02" id 1

create vlan "data_vlan"
configure vlan data_vlan tag 1001
configure vlan data_vlan add ports 19 tagged

configure vlan data_vlan add ports 1
</code>

<code config XOS-02.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 192.168.255.2 255.255.255.252

configure mlag ports convergence-control fast
create mlag peer "X350-24t-01"
configure mlag peer "X350-24t-01" ipaddress 192.168.255.1
enable mlag port 1 peer "X350-24t-01" id 1

create vlan "data_vlan"
configure vlan data_vlan tag 1001
configure vlan data_vlan add ports 19 tagged

configure vlan data_vlan add ports 1
