EXOS - MSTP - BPDU restrict error

KlausD — Thu, 01 Sep 2022 06:41:13 GMT

Hello,

When configuring MSTP as suggested here
https://extremeportal.force.com/ExtrArticleDetail?an=000081467&q=exos%20mstp
I get this
Error: Port 1 is not a member of STP domain s1

To fix it:
#configure stpd s0 delete Default ports 1
#configure stpd s1 add vlan Default ports 1

Now I want to run:
#configure stpd s1 ports edge-safeguard enable 1
Error: Setting safeguard in MSTI is not allowed

Questions:
- Should ports be in the CIST s0 or in MSTI s1?
- How would I configure edge-safeguard and bpdu-restrict for ports that are in MSTI s1 but
can only be configured for stpd s0 - where there are no ports?
- What am I missing?

Thank you,
Klaus

Did you look into ELRP as an alternative to mstp?

In MSTP, configuring edge safeguard at CIST will be inherited in all MSTIs.
In MSTP, an edge port needs to be added to a CIST before adding it to an MSTI.

Per EXOS 31.7 user guide, page 1321 "MSTP Edge Safeguard"

Thank you Adrian,

I am confused by this:
"In MSTP, an edge port needs to be added to a CIST before adding it to an MSTI."
Should I run this command
#enable s1 auto-bind vlan 1-4094
or should I keep all ports in CIST s0?
