Table 2-8 Enabling/disabling jumbo frames' passing a card
Enable Jumbo frames to pass the card on a
specified slot, and set the maximum length
of Jumbo frames allowed to pass the card
Disable Jumbo frames from passing the card
on a specified slot
By default, jumbo frames are allowed to pass cards.
Note:
The system supports discrete values of Jumbo frame lengths ranging from 1536 to
10240. However, effective Jumbo frame values fall into several sections: the effective
Jumbo frame value for the 1536-1552 section is 1552, that for the 1552-9022 section is
9022, that for the 9022-9122 section is 9122, and that for the 9122-10240 section is
10240.
2.2.9 Setting Broadcast/Multicast Suppression on Ethernet Port
To prevent port congestion resulting from broadcast/multicast packet flooding, the
switch supports broadcast/multicast suppression. You can enable broadcast/multicast
suppression by setting the speed percentage or bandwidth values..
Perform the following configuration in Ethernet port view.
