Hello,
My post concerns the new technology Stackwise-Virtual on 3850-XS-E.
I didn't find a lot of informations appart these informations:
- It's only compatible with version Denali 16.3.3.
- It works only on 2x 3850 and no more.
- We have to configure SVL link and optionnaly DAD.
- Only port 45-48 are compatible for SVL link
My questions concerns 2 parts:
1) The optimisation of my configuration.
2) The management of the active standby.
1)
Concerning my configuration, i do the following:
On switch 1 and 2:
stackwise-virtual
domain 100
!
interface range te1/0/47 - 48
stackwise-virtual link 1
!
interface te1/0/46
stackwise-virtual dual-active-detection
Question:
- Is it the optimal configuration (I try through port-channel but it didn't work)?
- Concerning stackwise-virtual link can we use other than id 1?
2)
I also try to search information concerning the management of standby and master state but without success.
By searching through command line I see:
show switch
Switch/Stack Mac Address : 70f3.5a0f.0600 - Local Mac Address
Mac persistency wait time: Indefinite
H/W Current
Switch# Role Mac Address Priority Version State
------------------------------------------------------------
*1 Active 70f3.5a0f.0600 1 V02 Ready
2 Standby 70f3.5a11.6500 1 V02 Ready
Stack Port Status Neighbors
Switch# Port 1 Port 2 Port 1 Port 2
--------------------------------------------------------
1 OK DOWN 2 None
2 OK DOWN 1 None
It's seems to use the stack logic concerning role management.
Question:
- If my understanding is right virtual stacking is hybrid between VSS and stack:
I configure the "virtual-stacking" as a VSS through VSL link and DAD.
I configure switch ID and priority as a normal stack.
Is it correct?
3)
If it is correct for example, if I want switch 1 be the master for control plane I have to do the following:
On switch 1
switch 1 priority 15
stackwise-virtual
domain 100
!
interface range te1/0/47 - 48
stackwise-virtual link 1
!
interface te1/0/46
stackwise-virtual dual-active-detection
!
On switch 2
switch 1 renumber 2
switch 2 priority 14
stackwise-virtual
domain 100
!
interface range te1/0/47 - 48
stackwise-virtual link 1
!
interface te1/0/46
stackwise-virtual dual-active-detection
Thank you for your help.
Best regards,
MC.
