DHCP che non va...

[ottobrerosso]

Ciao a tutti,
ho ampliato la mia "infrastruttura" aggiungendo un Catalyst 3750.
Tutto bene sulla parte di configurazione fino a quando mi sono imbattuto nel DHCP.
I pool DHCP sono configurati sul Router 1841, in particola 3 pool DHCP e 3 subinterface.
Questa la configurazione:

Ho provato a collegare il cavo di rete del PC su una interfaccia in ogni vlan ma niente da fare, non mi prende l'indirizzo ip....
Cos'è che non va ?
Grazie!

Ciao,
risolto! Erano sbagliati i pool DHCP
Ecco la configurazione giusta:

no ip dhcp use vrf connected
ip dhcp excluded-address 10.135.100.62
ip dhcp excluded-address 10.10.11.254
ip dhcp excluded-address 10.96.8.6
!
ip dhcp pool LAN
network 10.96.8.0 255.255.255.248
default-router 10.96.8.6
dns-server 8.8.8.8 8.8.4.4
lease 0 8
!
ip dhcp pool Static-Wifi
host 10.135.100.1 255.255.255.192
client-identifier 01d4.c9ef.54d7.4b
dns-server 8.8.8.8 8.8.4.4
default-router 10.135.100.62
!
ip dhcp pool WiFi
network 10.135.100.0 255.255.255.192
dns-server 8.8.8.8 8.8.4.4
default-router 10.135.100.62

lease 0 3
!
ip dhcp pool VLan1
