Hello,
We are closing a ring with 3 extreme switches, 2 Summit 48si and one
Summit300-48, last one is the master for the eaps domain, we already have
control vlan and protected vlan plus stpd.
When a link fail the eaps protocol activate the backup link, we don´t see
loss packet, the problem is when the primary link get up we get lost
connectivity for 4 seconds (2 ping packets). This is the fwrddelay of stp.
how can I get the same response when the primary link fail???
This is the output:
