Configuring a Smartlink between 4800G and 2x5500G

[LLarouanne]

Hello,

First of all, excuse my English, I am French and do not speak very good English, I went through the Google translator.

My question is about the feature "Smartlink" of 5500G.

I made an installation using this feature between two 5500G and 4800G (the feature being present in both products).

Here is my network diagram:

5500G(1) - Port 1/0/1 et 2/0/1 ======= Aggregat ====== 5500G(2) - Port 1/0/13 et 1/0/14

     |                                                                                                        |

port 1/0/16                                                                                   Port 1/0/15

     |                                                                                                        |

      ----------------- Port 1/0/15 - 4800G - Port 1/0/16 --------------

 Explanation:

5500G is connected both to each other by an aggregate link, and the 4800G is connected via a link on a 5500G and the other connection to the 2nd 5500G.

I create a VLAN dedicated to messages "flush" of the 3 Smartlink equipment.

Here's my setup on the 5500G (1):

link-aggregation group 1 mode manual

vlan 42

 description Smartlink

 name Smartlink

interface GigabitEthernet1/0/1

 smart-link flush enable control-vlan 42

 speed 1000

 port link-type hybrid

 port hybrid vlan 1 to 11 42 tagged

 flow-control

 broadcast-suppression pps 3000

 undo jumboframe enable

 port link-aggregation group 1

 apply qos-profile default

interface GigabitEthernet2/0/1

 smart-link flush enable control-vlan 42

 speed 1000

 port link-type hybrid

 port hybrid vlan 1 to 11 42 tagged

 flow-control

 broadcast-suppression pps 3000

 undo jumboframe enable

 port link-aggregation group 1

 apply qos-profile default

// Port connected to 4800G

interface GigabitEthernet1/0/16

 smart-link flush enable control-vlan 42

 duplex full

 speed 1000

 port link-type trunk

 port trunk permit vlan 1 to 11 42

 broadcast-suppression pps 3000

 undo jumboframe enable

 apply qos-profile default

Here's my setup on the 5500G (2):

link-aggregation group 2 mode manual

vlan 42

 description Smartlink

 name Smartlink

interface GigabitEthernet1/0/13

 smart-link flush enable control-vlan 42

 speed 1000

 port link-type hybrid

 port hybrid vlan 1 to 11 42 tagged

 flow-control

 undo jumboframe enable

 port link-aggregation group 2

 apply qos-profile default

#

interface GigabitEthernet1/0/14

 smart-link flush enable control-vlan 42

 speed 1000

 port link-type hybrid

 port hybrid vlan 1 to 11 42 tagged

 flow-control

 undo jumboframe enable

 port link-aggregation group 2

 apply qos-profile default

#

// Port connected to 4800G

interface GigabitEthernet1/0/15

 smart-link flush enable control-vlan 42

 duplex full

 speed 1000

 port link-type trunk

 port trunk permit vlan 1 to 11 42

 undo jumboframe enable

 apply qos-profile default

# 

Here's my setup on the 4800G (the one that manages the Smartlink):

vlan 42

 description Smartlink

 name Smartlink

smart-link group 1

 protected-vlan reference-instance 0 to 32

 flush enable control-vlan 42

// Primary link to the 5500G (1)

interface GigabitEthernet1/0/15

 port link-type trunk

 port trunk permit vlan 1 to 11 42

 broadcast-suppression pps 3000

 undo jumboframe enable

 stp disable

 port smart-link group 1 master

#

// Secondary link to the 5500G (2)

interface GigabitEthernet1/0/16

 port link-type trunk

 port trunk permit vlan 1 to 11 42

 broadcast-suppression pps 3000

 undo jumboframe enable

 stp disable

 port smart-link group 1 slave

#

My question is this: My setup is correct??

I ask this because I do not see a message "flush " arrived on my 5500G (1) when I executed the command "display smart-link flush". My 5500G (2) receives a message "flush" well when the primary link (the one that is brewed on the 5500G (1)) goes down, but not vice versa ...

On the 4800G, in normal operation (primary link connected to 5500G(1)), the output of the command "display smart-link group 1" is correct : the port 1/0/16 is standby and the primary link (1/0/15) is active.

Another question, I'll have to create two additional resilience by using the same feature on two other 4800G, should I create two vlans to monitor the loop??

thank you in advance for your response and the time you have me granted. 

Laetitia.
