Whats up 🙂
We now have an workplace with this topology :
ISP router < – > Switch_01 < – > Switch_02.
The Switches are Netgear GS752TPv2, with a close to manufacturing facility default configuration. So RTSP is enabled with default settings.
The DHCP server is a Home windows Server, plugged on Switch_01.
For an odd purpose, after we plug a tool (laptop) on the switches, it takes almost 1 minute to get the community up and operating on Home windows.
At first, I believed that the DHCP was the problem however after digging into switches logs, it seems that STP provides almost 30 to 50 seconds earlier than triggering after the port goes up :
<182>1 2023-11-19T17:34:00.373+1:00Z 10.113.3.12-1 STP-6-PORT_STATE proto_stp.c(820) %% Port GigabitEthernet31 shifting from Blocking to Forwarding
<182>1 2023-11-19T17:33:58.373+1:00Z 10.113.3.12-1 STP-6-PORT_STATE proto_stp.c(820) %% Port GigabitEthernet31 shifting from Disabled to Blocking
<182>1 2023-11-19T17:33:19.783+1:00Z 10.113.3.12-1 LLDP-6-NEIGHBOR_DISCOVER proto_lldp.c(5197) %% New neighbor on port GigabitEthernet31: Chassis ID 00:00:00:00:00:00, Port ID C0:3E:BA:XX:XX:XX
As you may see, the machine is plugged at 17:33:19 and STP triggers at 17:33:58 with a 2 second blocking earlier than forwarding.
Is that this a standard delay ? What might trigger this ?
Thanks ! 🙂
