Select two PCs within a department to perform ping tests and verify whether Layer 2
interworking within the department is normal.

The following example uses two PCs (PC1 and PC2) in department A. The two PCs
communicate at Layer 2 through ACC1. If they can ping each other successfully, Layer 2
interworking is normal.
Users in department A and department B communicate at Layer 3 through VLANIF
interfaces on CORE. If PC1 and PC3 can ping each other successfully, users in the two
departments can normally communicate at Layer 3 through VLANIF interfaces. The ping
command is similar to that in step 1.
<PC1>
ping 10.10.10.100
//Assume that PC2
automatically obtains an IP address 10.10.10.100 through DHCP.

PC1 can ping PC2
successfully, indicating that
Layer 2 interworking between
PC1 and PC2 is normal.

The following example uses department A. Generally, you can ping a public network
gateway address from PC1 to verify whether PC1 can access the Internet. The public
network gateway address is the IP address of the carrier device to which the egress
router connects. If the ping test succeeds, intranet users can access the Internet
normally. The ping command is similar to that in step 1.
Select one PC from each department to ping a public network address and verify
whether intranet users of the company can access the Internet normally.
