3Com 5500 PXE broadcast intermittent dropped issues

hi,

 

I'm running a desktop virtualization environment with ServerPark VDI.

The diskless desktops from VLan2 will bootup via PXE, and obtain VDI image from VLAN2.

both coreswitch and distribution switch are 3cOM 5500

I'm facing a situation where the client  during PXE bootup, has a 50% chance that it will not able to obtain the server IP. Upon restarting 1-5 times, the client will then able to find the VDI server IP, and boot up successfully.

 

 

 

Server/VLAN2/

 dhcp-server 1 ip  10.71.2.16 10.71.2.11 10.71.2.12   // 10.71.2.16 is the VDI server IP

interface GigabitEthernet1/0/2

 stp edged-port enable

 broadcast-suppression pps 3000

 port access vlan 2

 undo jumboframe enable

 apply qos-profile default

 

Client/VLAN6

interface Ethernet1/0/2

 stp edged-port enable

 broadcast-suppression pps 3000

 port access vlan 6

 undo jumboframe enable

 apply qos-profile default

 

When we setup the VDI environment in Cisco 2960 switches, it will work perfectly once PortFast + DHCPrelay is configured.

 

attached is the config files for your reference.

thanks in advance!
