VES-1000 Series Ethernet Switch
Port Setup 6-9
Table 6-5 Uplink Port Setup
LABEL DESCRIPTION
Port Number This read-only field displays the port index number you are now configuring.
Name Choose a descriptive name for identification purposes.
Default Priority This priority value is added to incoming frames without a (802.1p) priority tag (this is not the
same as port priority talked about below).
Active The Ethernet port is disabled by default.
Type This read-only field displays the type of port you are currently configuring.
Speed This is the speed of the Ethernet uplink connection. Select Auto , 10M or 100M from the
drop-down list box.
Duplex The duplex mode can be half (meaning traffic is transmitted in one direction at a time) or
full (meaning traffic is simultaneously transmitted in both directions). If
Auto is selected in
the Speed field, the Duplex drop-down list box will only display N/A .
Flow Control IEEE802.3x flow control manages the sending of traffic so the sending line card does not
transmit more than the receiving line card can process. This helps prevent traffic from
being dropped and having to be resent. Select the checkbox to enable flow control.
Static MAC
Address Filtering A static MAC address entry is an address that you manually enter into the MAC address
learning table. Static MAC addresses do not age out. This may reduce unicast flooding.
The devices with MAC addresses on this list can only receive traffic on this port on the line
card.
Number This is the ID number of the device entry.
Active Select this check box to turn on static MAC address forwarding for this entry’s MAC
address. The device with this entry’s MAC address can only receive traffic on this port on
the line card.
Clear this check box to turn off static MAC address forwarding for this entry’s MAC
address. The device with this entry’s MAC address can only receive traffic on this port on
the line card.
Static MAC
Address Enter the MAC address in valid MAC address format, that is six hexadecimal character
pairs.
Spanning Tree
Protocol Select the check box to use STP on this port.
Priority Configure the priority for each port here. Priority decides which port should be disabled
when more than one port form a loop in a switch. Ports with a higher numeric priority value
are disabled first. The allowed range is between 0 and 255 and the default value is 128.
Path Cost Path cost is the cost of transmitting a frame onto a LAN through that port. It is assigned
according to the speed of the media. The slower the media, the higher the cost.
VLAN Ingress Rule These fields are available when you enable IEEE 802.1 VLAN on the VES.
Default VLAN ID Default VLAN ID is the PVID (Port VLAN ID) assigned to untagged frames or priority
frames (0 VID) received on this port.
GVRP GVRP (GARP VLAN Registration Protocol) is a registration protocol that defines a way for
switches to register necessary VLAN members on ports across the network. Select this
check box to enable GVRP and propagate VLAN information beyond the local switch.
VLAN Acceptable
Frame Type Select All if you want the port to accept both tagged and untagged incoming packets (to
that port). Choose Tagged if you want the port to accept just tagged incoming packets (to
that port).
