Configuration/ Uplink Bridged Video Connections Help

You create a video bridge on the uplink by first creating an uplink bridge on a 100/1000 Ethernet or a 10 GE port using a VLAN ID. Then enter the multicast aging period and IGMP query interval for video traffic when creating the video paths. .

To refresh the data displayed in the Bridge Connections table, click the Refresh button.

To create a bridge connection, click the Create button.

To remove a bridge connection, click the Delete button.

To modify the bridge connection, click the Modify button.

To add a path, click the Add Path button.

To show a path, click the Show Path button.

Video Source

Port

The port assigned to this interface.

VLAN ID

The Virtual LAN Identifier for the IP Interface. If the VLAN ID specified is non-zero, all traffic destined to this interface should be configured with this VLAN ID.

Default is 0.

S-Tag ID

Outer tag SLAN ID in Q-in-Q configurations.

Type

Type of bridge configuration.

Uplink 802.1Q

MVR

Ingress Rule-Group

The index number for packet-rule-record(s ) when adding multiple filters for ingress interfaces.

Egress Rule-Group

The index number for packet-rule-record(s ) when adding multiple filters for egress interfaces.

MCast Control List

Defines which multicast addresses the remote end video can access. A multicast control list entry of 0 enables subscriptions up to the number of maximum video streams on the interface without control list checking. Video streams can be configured on 10/100, GigE , and other interfaces.

Statistics Enabled

Whether on demand IP statistics are enabled on this interface.

RSTP

Whether Rapid Spanning Tree Protocol is enabled.

Strip And Insert

Defines how VLAN tags are stripped and inserted as they traverse the ingress and egress of the device.

The untagged bridge set the strip insert parameter to TRUE, the tagged bridge set the strip insert parameter to FALSE. When the strip insert parameter is set to true, the VLAN ID is stripped and inserted, when the strip insert parameter is set to FALSE, the VLAN ID remains and is passed on untouched.

Default is false.

Send ARP Requests

Enables ARP broadcast support. When the device receives a broadcast frame it checks to see if it is an ARP protocol packet by looking up an IP address in a database which maintains learned IP addresses. If the packet is an ARP packet, the device compares and filters the requested IP address with the current forwarding table. When a match is found, the ARP broadcast is forwarded out the interface with the appropriate host.

The host then replies to the ARP with a standard response. If a match is not found, the ARP is filtered and is dropped.

Default is false.

Discard Non-ARP Broadcast

Enables the filtering that will not propagate broadcasts send from the upstream down to the device. Ports configured as uplinks will send broadcasts upstream.

IP Address Learning

If true, snoop unicast packets to build ARP table.

Default is false.

Unicast Address Learning

If true, snoop unicast packets to build MAC paths.

Default is false.

Maximum Unicast

Maximum number of unicast addresses for interface.

Multicast Address Learning

If true, snoop multicast packets for IGMP joins/leaves.

Default is false.

Forward Via Unicast Paths

If true, attempt to forward via unicast MAC paths.

Default is false.

Forward Via Multicast Paths

If true, attempt to forward via multicast MAC paths.

Default is false.

Forward Via Default Paths

If true, attempt to forward via VLAN default paths.

Default is false.

Custom DHCP

If TRUE, forwards broadcast DHCPOFFER or DHCPACK packets even if bridgeFilterBroadcast is TRUE for that interface.

Default is false.

Flood Unknown

Provides the ability to toggle the flooding of unknown unicast destination frames.

When set to True, the system always forwards frames with an unknown unicast MAC if the bridge is set for forward to unicast .

When set to False, the system always discards frames with an unknown unicast MAC if the bridge is set for forward to unicast . Any frame that does not find a match in the forwarding table will be discarded.

For uplink bridges, the default settings for this parameter is false.

Flood Multicast

Allows the device to flood all multicast traffic received on a bridge out to all other ports in the VLAN . By default, this parameter is set to false for all bridge types.

Dynamic Filtering

Enables/disables a dynamic IP filter on downlink bridges to prevent users with a statically configured IP address from bypassing DHCP security enforcement. This filter blocks users from accessing the network using anything other than valid DHCP offered IP address.

DHCP Learn

The type of learning on DHCP server.

Values:

none: IP address and Mac address are not learned from DHCP packets.

mac: MAC addresses are learned from DHCP packets.

ip : IP addresses are learned from DHCP packets.

VLAN ID CoS

Specifies the value loaded into the CoS field of the VLAN header when an untagged packet receiver on this interface is tagged ( VLAN ID inserted) for bridging.

Value range is 0 to 7, with the lowest priority being 0 and the highest priority 7.

Default is 0.

Outgoing CoS Option

Specifies whether to insert the VLAN COS bits on packets bridge through this interface.

Values:

Disable: leave any existing COS values unchanged.

All: replace the current COS values in all VLAN headers in tagged and untagged packets originating and transported through this device.

Disable: COS setting is untouched.

Default: disable

Outgoing CoS Value

The COS value for outgoing tagged packets. It specifies the value used to overwrite any existing COS value in the VLAN header.

Value range is 0 to 7. Default value is 0.

Applicable only if interface sends tagged packets and Outgoing CoS Option is set to all.

S-Tag TPID

Identifies the type of VLAN ID used. Typically set to 8100.

S-Tag StripAndInsert

If true, enable S-tag tagging on this interface.

Default is false.

S-Tag Outgoing CoS Option

Determines s-tag COS settings on packets bridged out this interface:

disable - s-tag COS setting just passed as received.

all - s-tag COS will be set with S-Tag Outgoing CoS Value.

Default is disable

S-Tag CoS

The s-tag COS to be used when doing s-tag insertion.

Default is 0

S-Tag Outgoing CoS Value

The s-tag COS value loaded into outgoing tagged packets.

Applicable only if interface sends S-tagged packets and S-Tag Outgoing CoS Option is All.

Default is 0

Accept PPPoA Packets

Not supported.
