configuration for the receiving IP subnet.
When the DHCP server receives the DHCP request, it allocates a free IP address for the DHCP client from its
scope in the DHCP client's subnet and sends a DHCP Response back to the DHCP Relay Agent. The DHCP
Relay Agent then broadcasts this DHCP Response packet received from the DHCP server to the appropriate
client.
Pinging
The following options can be set for pinging:
The IP address of the host you want to ping.
The packet count number (from 1 to 999, or 0 for an infinite packet count).
The packet size (from 0 to 1500).
The timeout value (from 0 to 999).
To set the ping options:
1. Select
IP Networking
from the
Advanced Management Menu
.
2. Select
Ping
.
3. Highlight each item one at a time and press
Enter
.
4. Set each option in the screen.
5. Press

Aging
- Aging is an operation used so a switch can maintain its learning table. If a network device does not
send any packets in the aging time, its MAC address entry in the learning table will be removed. This operation
is called aging.
Flooding
- Whenever a packet is sent to a switch, the switch will try to find the destination port of the packet by
looking it up in the learning table. It will then forward it. If the DA (destination MAC address) of the packet
cannot be found in the learning table, the switch will forward it to every port. This operation of a switch is called
flooding. These flooding packets may cause unnecessary network traffic in the network.
Multicast limit
s work
like broadcast, but the packet is only sent to the member client, not all ports.
Static Filtering
Static Filtering allows you view, add, delete, or search all source or destination addresses to be filtered.
