Configure Distributed Trunking on HP Procurve and MEC on Cisco VSS

Distributed Trunking is the 'equivalent' of the vPC on the Cisco Nexus Series. It's a link aggregation technique which can be used even if the host is connected on 2 differents switchs. The following design has been built between 2 HP 5400 and 2 Cisco 4500 in VSS mode.



  • Configuration on the Cisco Switch:

interface Port-channel20
 description TO-HP-DT
 switchport
 switchport mode trunk
!
interface TenGigabitEthernet1/5/4
 description TO-HP-DT-1
 switchport mode trunk
 channel-group 20 mode active
!
interface TenGigabitEthernet2/5/4
 description TO-HP-DT-2
 switchport mode trunk
 channel-group 20 mode active


  • Configuration of the HP 1:
    • Configure ISC
trunk B7,E8 trk10 lacp
switch-interconnect trk10
vlan xxx
 tagged trk10
vlan xxx
 tagged trk10
...
    • Configure the keepalive 
interface D20
   name "Keep-Alive"
   exit
vlan 900
   name "VLAN900"
   untagged D20
   ip address 192.168.100.1 255.255.255.0
   exit
distributed-trunking peer-keepalive vlan 900
distributed-trunking peer-keepalive destination 192.168.100.2
    • Configure the dt-lacp between the VSS and the HP:
trunk A1,B1 trk1 dt-lacp

  • Configuration of the HP 2:
    • Configure ISC
trunk B7,E8 trk10 lacp
switch-interconnect trk10
vlan xxx
 tagged trk10
vlan xxx
 tagged trk10
...
    • Configure the keepalive 
interface D20
   name "Keep-Alive"
   exit
vlan 900
   name "VLAN900"
   untagged D20
   ip address 192.168.100.2 255.255.255.0
   exit
distributed-trunking peer-keepalive vlan 900
distributed-trunking peer-keepalive destination 192.168.100.1
    • Configure the dt-lacp between the VSS and the HP:
trunk A1,B1 trk1 dt-lacp
  • Validation:
HP-1# show switch-interconnect
Port         : Trk10
Status       : Up
Active VLANs : 1,100,200,300


HP-1# show distributed-trunking statistics peer-keepalive
DT peer-keepalive Status : Up

HP-1# show  distributed-trunking consistency-parameters trunk trk1

Allowed VLANs on Local : 1,100,200,300
Allowed VLANs on Peer  : 1,100,200,300

HP-1# show  lacp distributed

                             Distributed LACP

Local Port Status:

       LACP    Trunk   Port            LACP    Admin  Oper
  Port Enabled Group   Status  Partner Status  Key    Key

Remote Port Status:

Partner's information:

                  LACP port                        Admin  Oper   Port    Port
Port      Flags   Priority  Dev ID          Age    key    Key    Number  State

Te2/5/4   SA      0         40a8.f07b.a400   4s    0x0    0x0    0x271A  0x3D


Some remarks:
- ISC is only supported in MST mode
