Aggregation and redundancy | FortiGate / FortiOS 7.6.4 | Fortinet
This example creates an aggregate interface on a FortiGate-140D POE using ports 3-5 with an internal IP address of 10.1.1.123, as well as the administrative access to HTTPS and SSH.
Switch Port Configuration and Troubleshooting
In most cases, this will be because either the adapter or the switch port has been manually configured. If a host is set to a fixed configuration and the switch is set to auto-negotiate,
[All About Switches] An Access Switch Cannot Ping the Gateway
Involved Products and Versions Modular switches running V200R007 and later versions Networking As shown in Figure 1-1, ME60 is the gateway of SwitchB,
Cant ping across switchs on managment IP. | Switching
Often a single switch will connect to the firewall and the other downstream switches connect back to this as a aggregation point. Looking closer at your output I see the sw1 seems to be missing a default
Device Cannot Ping Gateway
Check the status of the interfaces between the access and core switches (including the convergence switches) and ensure that the instances to which the member VLANs of the interfaces belong are in
Core to access switch ping working and access to core is not pinging
Look for me Access switch do not aware the IP coming from Core switch to reach back. so make sure Access switch aware routing setup correctly using ip route command.
Core ARP table issues
Triple check that the default gateway and subnet mask are set correctly on all these hosts, and the core switch. The core l3 switch may be using proxy arp which can hide these misconfigurations and cause
I can''t ping to the switch before I ping the core!
Ideally, try pinging it from its LAN. If you can reach it from there then it''s probably a firewall/access control issue. If you can''t reach it even from its LAN then it''s possible that the
Solved: LIVEcommunity
The first problem is the firewall itself can not ping directly connected device by using "ping source x.x.x.x host y.y.y.y" command. Every sub interface has management profile assigned.
