Chapter 5. Configuring Slots and Ports on a Switch
NETGEAR 8800 User Manual
Note:
Only jumbo frame-to-normal frame fragmentation is supported.
Jumbo frame-to-jumbo frame fragmentation is not supported.
To configure VLANs for IP fragmentation:
1.
Enable jumbo frames on the incoming port.
2.
Add the port to a VLAN.
3.
Assign an IP address to the VLAN.
4.
Enable ipforwarding on the VLAN.
5.
Set the MTU size for the VLAN, using the following command:
configure ip-mtu <mtu> vlan <vlan_name>
The ip-mtu value ranges between 1500 and 9194, with 1500 the default.
Note:
To set the MTU size greater than 1500, all ports in the VLAN must
have jumbo frames enabled.
IP Fragmentation within a VLAN
The NETGEAR 8800 supports IP fragmentation within a VLAN. This feature does not require
you to configure the MTU size. To use IP fragmentation within a VLAN:
you to configure the MTU size. To use IP fragmentation within a VLAN:
1.
Enable jumbo frames on the incoming port.
2.
Add the port to a VLAN.
3.
Assign an IP address to the VLAN.
4.
Enable ipforwarding on the VLAN.
If you leave the MTU size configured to the default value, when you enable jumbo frame
support on a port on the VLAN you will receive a warning that the ip-mtu size for the VLAN is
not set at maximum jumbo frame size. You can ignore this warning if you want IP
fragmentation within the VLAN, only. However, if you do not use jumbo frames, IP
fragmentation can be used only for traffic that stays within the same VLAN. For traffic that is
sent to other VLANs, to use IP fragmentation, all ports in the VLAN must be configured for
jumbo frame support.

Link Aggregation on the Switch
The link aggregation (also known as load sharing) feature allows you to increase bandwidth
and availability by using a group of ports to carry traffic in parallel between switches. Load
sharing, link aggregation, and trunking are terms that have been used interchangeably in
NETGEAR documentation to refer to the same feature, which allows multiple physical ports
