Cisco switch 2960 host taking time to turn on LAN

[13jobsp90]

I have a switch 2960 model, in which hosts connected to it are taking around 30 secs to turn on lan connection  after waking up from sleep mode. Currently it is running on PVST mode. Is there any option to make it fast to turn on LAN?

how is the configuration looks like on interface config, make sure switchport porfast configured

interface commands are just 2 commands " switchport access vlan & swtichport mode access" only these two. For each host connected interfaces  we have to give "spanning-tree portfast" command along with the above?

That OK' then it can host not get IP via dhcp fast.

Check with static IP

example : (this command speed up the process) check and let us know if that improve?

interface x/x
switchport access vlan xx
switchport mode access
switchport voice vlan yy
spanning-tree portfast
spanning-tree bpduguard enable

this standard config, the delay can be DHCP or in the path. so need to be address different if that above config not fix the issue.

what is the difference between these 2 commands ?

spanning-tree portfast
spanning-tree bpduguard enable

[balaji.bandi]

By using that command is the issue fixed ?

Suggest to spend some time reading the documents as i was suggested before, you can find the command syntax and different for reference :
