I'm trying to configure a new subnet for my users. DHCP is configured on the switch SW1.
The topology looks like this : SW1 <===> SW2 <===> PC
There is an etherchannel + trunk link between SW1 and SW2.
For whatever reasons, I cannot ping the PC. It gets an IP just fine.
Here is my configuration on SW1:
ip dhcp class rangeuser ip dhcp pool UsersLAN network 10.239.146.0 255.255.255.0 domain-anme xx.com dns-server 172.30.184.5 172.30.184.4 default-router 10.239.146.1 lease 0 2 class rangeuser address range 10.239.146.10 10.239.146.250 address 10.239.146.82 client-id 0114.b31f.17c5.a7 int po24 switchport mode trunk int vlan11 ip address 10.239.146.5 255.255.255.0
And on SW2:
int po24 switchport mode trunk int gi2/0/41 switchport access vlan 11 switchport mode access switchport voice vlan 30 spanning-tree portfast spanning-tree bpduguard enable
Show ip dhcp binding displays the lease. But when I try to ping using source interface vlan 11, it simply does not work. If I put back the access port into the old user vlan (vlan 10), then I can ping just fine with my switch.
What's going on here ?
