SSP S410 Trunk Interface configuration

Issue/Introduction

I’m trying to configure trunk interface on SSP S410. Thus far I only see documentation on how enable vlan-trunk on interface but not how one would configure Trunk interface to assign IP for trunked VLANs. Can you please provide this info.

Resolution

VLAN trunking and IP configuration are handled within the Edge SWG (ProxySG) application running on the ISG (SSP host), not by the host itself.

• Trunking is managed at the application level, meaning the ISG host simply provides the physical interfaces, while Edge SWG (ProxySG) handles VLAN tagging and traffic routing.
  
  
• IP addresses are assigned within Edge SWG (ProxySG), not on the ISG host. You configure VLAN interfaces and assign IPs directly in the Edge SWG (ProxySG) CLI or GUI.
  
  
• The ISG host doesn’t support VLAN-based IP assignment—it just passes traffic to the application.
  
  
• If you're using VLANs, make sure the physical interface on the SSP is connected to a trunk port, and then configure VLAN subinterfaces and IPs inside Edge SWG (ProxySG).

 

Configuration on SSP/ISG:

ISG(config)# interface eth0
ProxySG(config-if)# vlan-trunking enable
ProxySG(config-if)# exit

Sample ProxySG CLI Configuration 

# Enter configuration mode
ProxySG# configure terminal

# Create VLAN subinterfaces on eth0
ProxySG(config)# interface eth0.100
ProxySG(config-if)# ip address <IP_Address> <Subnet_Mask>
ProxySG(config-if)# exit

ProxySG(config)# interface eth0.200
ProxySG(config-if)# ip address <IP_Address> <Subnet_Mask>
ProxySG(config-if)# exit
