Technical Tip: Hardware switch interface behavior

[hhasny]

Description	This article describes the behavior of an interface configured as a hardware-switch.
Scope	FortiGate.
Solution	When an interface is configured as a hardware switch interface, the status of the interface will remain as UP even when there is no connection. Upon checking the routing table, the connected route of the interface will remain. This is expected behavior. get router info routing-table all Codes: K - kernel, C - connected, S - static, R - RIP, B - BGP O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2 i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area * - candidate default Routing table for VRF=0 S* 0.0.0.0/0 [10/0] via 10.47.15.254, VLAN18, [1/0] C 10.47.0.0/20 is directly connected, VLAN18 C 10.100.64.0/30 is directly connected, Test-HW-SW1 C 10.100.65.0/30 is directly connected, Test-HW-SW2 C 192.168.2.0/24 is directly connected, lan C 202.82.246.56/29 is directly connected, lan Click on the image below to zoom in.
