1588 ExtremeWare 7.7 Command Reference Guide
STP Commands
configure stpd max-hop-count
configure stpd <stpd_name> max-hop-count <hopcount>
Description
Specifies the maximum hop count of a BPDU until the BPDU is discarded in the specified MSTP STP
domain.
Syntax Description
Default
The default hop count of a BPDU is 20 hops.
Usage Guidelines
This command is applicable only in an MSTP environment.
If your STPD has the same name as another component, for example a VLAN, Extreme Networks
recommends that you specify the identifying keyword as well as the name. If your STPD has a name
unique only to that STPD, the keyword
stpd
is optional.
You should not configure any STP parameters unless you have considerable knowledge and experience
with STP. The default STP parameters are adequate for most networks.
The range for the
<hopcount>
parameter is 6 through 40 hops.
In an MSTP environment, the hop count has the same purpose as the maxage timer for 802.1D and
802.1w environments.
Example
The following command sets the hop of the MSTP STPD, STPD2, to 30 hops:
configure stpd stpd2 max-hop-count 30

stpd_name Specifies an STPD name on the switch.
