TitleHow to configure MLAG with EXOS core switches to EOS edge switch
Question
What is the recommended configurations with  EXOS switches as the MLAG peers and an EOS switch as the upstream switch

 
Environment
  • Summit Series switches
  • SecureStack C-Series
  • SecureStack B-Series
  • S-Series
  • MLAG
  • LACP
Answer
  • EXOS core 1
  • Specific example with one mlag port 10, ISC port 48, VLAN data tag ID 10, VLAN ISC_VLAN tag ID 999
 
create vlan data
configure vlan data tag 10
create vlan ISC_VLAN
configure VLAN ISC_VLAN tag 999
configure vlan ISC_VLAN ipaddress 192.168.1.1 255.255.255.0

configure vlan data add ports 10,48 tagged
configure vlan ISC_VLAN add ports 48 tagged

enable sharing 10 grouping 10 algorithm address-based L3_L4 lacp
enable sharing 48 grouping 48 algorithm address-based L3_L4 lacp 

create mlag peer "ISC_MLAG"
configure mlag peer "ISC_MLAG" ipaddress 192.168.1.2 vr VR-Default
enable mlag port 10 peer "ISC_MLAG" id 10 
 
  • EXOS core 2
  • Specific example with one mlag port 10, ISC port 48, VLAN data tag ID 10, VLAN ISC_VLAN tag ID 999
 
create vlan data
configure vlan data tag 10
create vlan ISC_VLAN
configure VLAN ISC_VLAN tag 999
configure vlan ISC_VLAN ipaddress 192.168.1.2 255.255.255.0


configure vlan data add ports 10,48 tagged
configure vlan ISC_VLAN add ports 48 tagged

enable sharing 10 grouping 10 algorithm address-based L3_L4 lacp
enable sharing 48 grouping 48 algorithm address-based L3_L4 lacp


create mlag peer "ISC_MLAG"
configure mlag peer "ISC_MLAG" ipaddress 192.168.1.1 vr VR-Default
enable mlag port 10 peer "ISC_MLAG" id 10
 
  • EOS (S-Series or SecureStack)
  • Specific example using LAG named lag.0.1 comprising of ports tg.1.49 and tg.2.49 aadminkey 10 VLAN name data with tag ID 10
 
set vlan create 10
set vlan name 10 data

set port lacp port tg.1.49 enable
set port lacp port tg.2.49 enable

set lacp aadminkey lag.0.1 10

set port lacp port tg.1.49 aadminkey 10
set port lacp port tg.2.49 aadminkey 10
set lacp singleportlag enable

set spantree portadmin tg.1.49 disable
set spantree portadmin tg.2.49 disable

set vlan egress 10 lag.0.1 tagged
Additional notes
  • EXOS show commands
 
show sharing
show sharing detail
show mlag port 10
show mlag peer
show lacp counters
  • EOS show commands
 
show port lacp port tg.1.49 status detail
show port lacp port tg.2.49 status detail

show port lacp port tg.1.49 status summary
show port lacp port tg.2.49 status summary

show port lacp port tg.1.49 counters
show port lacp port tg.2.49 counters

show lacp lag.0.1
show port status lag.0.1

show vlan portinfo port lag.0.1
