Hello, colleagues!
I need to insert option 82 information in dhcp-packets.
Try bootprelay - all work fine.
Trying dhcp-snooping - switch don't insert option 82 information.
My config:
enable ip-security dhcp-snooping vlan v74_Users port 16 violation-action none
enable ip-security dhcp-snooping vlan v74_Users port 20 violation-action none
enable ip-security dhcp-snooping vlan v74_Users port 21 violation-action none
enable ip-security dhcp-snooping vlan v74_Users port 26 violation-action none
enable ip-security dhcp-snooping vlan v74_Users port 27 violation-action none
configure trusted-ports 26 trust-for dhcp-server
configure ip-security dhcp-snooping information option
configure ip-security dhcp-snooping information check
configure ip-security dhcp-snooping information circuit-id vlan-information v74 vlan v74_Users
configure ip-security dhcp-snooping information circuit-id vlan-information v75 vlan v75_Users2
configure ip-security dhcp-bindings storage write-interval 1440
configure ip-security dhcp-bindings storage filename bind.txt.xsf
enable ip-security dhcp-bindings restoration
User_Guide say:
When DHCP relay is configured in a DHCP snooping environment, the relay agent IP address should be configured as the trusted server.
“configure trusted-servers {vlan} add server trust-for dhcp-server”
Should I add IP-address of DHCP-server or/and configure Extreme's switch as trusted-server? But I have "configure trusted-ports 26 trust-for dhcp-server"
Any ideas?
Thank you!
