EOS to XOS - Lag setup

EOS to XOS - Lag setup

So about to replace all the Enterasys's in our network.

In the old EOS configurations, the lag's have been added to each of the VLAN's. in setting up the new XOS switches, is this best practice? From my understanding most of the port setup is stripped when creating the LAG?? We have 3 LAG's in one switch associated with particular VLAN's.

Thx

For the second "show port 1 info det", you can see that port 1 has been added to LAG and is the master port. You can check it in:

Hi Dave,

The vlan membership of LAG always follow the membership of master port. That means, if there are three vlans already added to the master port, when you create a LAG, those three vlans will be added to LAG. Here is the example:

==== Three Vlans have been added to a normal port ====

* L7:U33.32 # sh port 1 info detPort: 1
Virtual-router: VR-Default
Type: UTP
Random Early drop: Unsupported
Admin state: Enabled with auto-speed sensing auto-duplex
Link State: Ready
Link Ups: 0 Last: --
Link Downs: 0 Last: --

VLAN cfg:
Name: V0801C, 802.1Q Tag = 801, MAC-limit = No-limit, Virtual router: VR-Default
Name: V2510D, 802.1Q Tag = 2510, MAC-limit = No-limit, Virtual router: VR-Default
Name: VLAN_100, 802.1Q Tag = 100, MAC-limit = No-limit, Virtual router: VR-Default
STP cfg:
STPD_01(enable), Tag=0801, Mode=EMISTP, State=DISABLED

Protocol:
Trunking: Load sharing is not enabled.

=== After enable LAG ===

* L7:U33.33 # enable sharing 1 grouping 1-2 lacp
Warning: STP port (1) is lost due to port is deleted from VLAN.
Warning: Any config on the master port is lost (STP, IGMP Filter, IGMP Static Group, MAC-Security, CFM, etc.)

* L7:U33.34 # sh sharing Load Sharing Monitor

Link State: A-Active, D-Disabled, R-Ready, NP-Port not present, L-Loopback
Load Sharing Algorithm: (L2) Layer 2 address based, (L3) Layer 3 address based

so previously when adding a LAG to a VLAN the below was used:
set vlan egress 100 lag.0.1 tagged

so just the Master Port of the chosen LAG to add to the VLAN.
configure vlan 100 1:1 tagged

Thx.
