Technical Tip: Name length limitation of any interface configured as a monitor-interface/pingsvr-monitor-interface in 7.6.0

[ydong01]

Description	This article describes that when configuring monitor-interface/pingsvr-monitor-interface, if the interface name length is over 7 characters, the new feature "FGSP support for failover with asymmetric traffic and UTM" will not work.
Scope	FortiGate v 7.6.0
Solution	There is a new feature in v7.6.0: FGSP support for failover with asymmetric traffic and UTM. When the Interface name has more than 7 characters, fgsp_route_health shows 0. The feature will not work: config system standalone-cluster ....     set monitor-interface "lag_trust" "lag_untrust"     << Over 7 characters end diagnose test application sessionsync 1 HA is not enabled sync context: sync-enabled=0, sync-tcp=1, sync-nat=1 sync-other=1, sync-exp=1, standalone-sync=1, mtu=0 ipsec-tun-sync=1 fgsp-peers-num=1, kernel-filters-num=1 fgsp-peers: vdom=0, ip/port=10.1.100.2:708 fgsp_route_health=0 mondev: Bundle_(0) When the Interface name is less than 7 characters, fgsp_route_health shows 1, the feature will not work: config system standalone-cluster ....     set monitor-interface "lag_t" "lag_u"          << Less 7 characters    end diagnose test application sessionsync 1 HA is not enabled sync context: sync-enabled=0, sync-tcp=1, sync-nat=0 sync-other=1, sync-exp=1, standalone-sync=1, mtu=0 ipsec-tun-sync=1 fgsp-peers-num=1, kernel-filters-num=6 fgsp-peers: vdom=0, ip/port=10.1.100.2:708 fgsp_route_health=1 The workaround is to reduce the interface name length to less than 7 characters.
