Misc Config

Collisions Retry Forever:

disable is in half duplex. If happen collision will retry 48

times and then drop frame. Enable is in half duplex. If happen collision will retry

forever.

Hash Algorithm:

CRC Hash or Direct Map for MAC address learning algorithm

IFG Compensation:

Internal Packet Gap time compensation configure. Select to

“Enable” or “Disable”.

802.1x Protocol:

enable or disable 802.1x protocol.

IGMP Query Mode:

recognizes different queries from clients or servers to decide

which Query will be the first priority. The modes are:

Auto Mode:

chooses the switch that has the smallest IP address to be set for

the IGMP Query mode.

Enable Mode:

enables the switch to be the IGMP Querier.

Disable Mode:

disables all other switches from being the IGMP Querier.

Switch Misc Config setting interface
