Configure LAN Properties

You can configure LAN properties for your RealPresence Group Series system in the local interface or the system web interface.

Procedure

  1. In the system web interface, go to Admin Settings > Network > LAN Properties.
  2. Configure the following LAN Options settings in the system web interface at Admin Settings > Network > LAN Properties > LAN Options.
    Setting Description
    Host Name

    (system web interface only)

    Indicates your system name. If the system discovers a valid name during setup or a software installation, the system automatically creates the host name. However, if the system finds an invalid system name, such as a name with a space, the system creates a host name using the following format: SystemType-xxxxxx, where xxxxxx is a set of random alphanumeric characters.

    IPv4 networks: The system sends the host name to the DHCP server to attempt to register the name with the local DNS server or look up the domain where the system is registered (if supported).

    IPv6 networks: You can leave this field blank since the system doesn’t support this function. However, Polycom recommends configuring the field to contain the registered host name.

    Domain Name

    (system web interface only)

    Identifies the domain your system belongs to.

    If the system doesn’t automatically obtain a domain name, enter one here.

    Autonegotiation

    (under General Settings in the local interface)

    Specifies whether the system should automatically negotiate the LAN speed and duplex mode per IEEE 802.3 autonegotiation procedures. If you enable this setting, the system sets LAN Speed and Duplex Mode to read-only.

    Polycom recommends that you use autonegotiation to avoid network issues.

    LAN Speed

    (under General Settings in the local interface)

    Specifies whether to use 10 Mbps, 100 Mbps, or 1000 Mbps for the LAN speed. Note that the switch must support the speed you choose. If you enable the Autonegotiation setting, this setting is read-only.

    Duplex Mode

    (under General Settings in the local interface)

    Specifies the duplex mode to use. Note that the switch must support the speed you choose. If you enable the Autonegotiation setting, this setting is read-only.

    Ignore Redirect Messages

    (system web interface only)

    Enables the system to ignore ICMP redirect messages.

    Polycom recommends that you enable this setting in most circumstances.

    ICMP Transmission Rate Limit (millisec)

    (system web interface only)

    Specifies the minimum number of milliseconds between transmitted packets. Enter a number between 0 and 60000. The default value of 1000 means the system sends 1 packet per second. If you enter 0, the system disables the transmission rate limit.

    This setting applies only to “error” ICMP packets. This setting has no effect on “informational” ICMP packets, such as echo requests and replies.

    Generate Destination Unreachable Messages

    (system web interface only)

    Generates an ICMP Destination Unreachable message if the system can’t deliver a packet to its destination for reasons other than network congestion.

    Respond to Broadcast and Multicast Echo Requests

    (system web interface only)

    When enabled, your system sends an ICMP Echo Reply message in response to a broadcast or multicast Echo Request that isn’t specifically addressed to the system.

    IPv6 DAD Transmit Count

    (system web interface only)

    Specifies the number of Duplicate Address Detection (DAD) messages to transmit before acquiring an IPv6 address. The system sends DAD messages to determine whether the address it is requesting is already in use.

    Select whether to transmit 0, 1, 2, or 3 DAD requests for an IPv6 address.

    Enable PC LAN Port This setting appears only for RealPresence Group 700 systems.

    Specifies whether the PC LAN port is enabled on the back of the system. Disable this setting for increased security.

    Enable LLDP

    (under General Settings in the local interface)

    Specifies if you want the system to advertise itself on the network using the Link Layer Discovery Protocol (LLDP). Enable if you want your system to operate on a virtual LAN (VLAN).

    Enable EAP/802.1X

    (under EAP 802.1X in the local interface)

    Enables EAP/802.1X network access. The system supports the following authentication protocols:
    • EAP-MD5
    • EAP-PEAPv0 (MSCHAPv2)
    • EAP-TTLS
    • EAP-TLS
    EAP/802.1X Identity

    (under EAP 802.1X in the local interface)

    Specifies the identity the system uses for 802.1X authentication. This setting is available only when you enable EAP/802.1X. You can’t leave this field blank.

    EAP/802.1X Password

    (under EAP 802.1X in the local interface)

    Specifies the password the system uses for 802.1X authentication. This setting is required when you use EAP-MD5, EAP-PEAPv0, or EAP-TTLS.

    Enable 802.1p/Q

    (under 802.1p/Q in the local interface)

    Enable if you want to configure your system with a virtual LAN (VLAN) and set link layer priorities.

    VLAN ID

    Identifies the VLAN you want your system to operate on. This setting is available only when you enable 802.1p/Q. You can use any value from 1 to 4094.

    Video Priority

    Sets the link layer priority of video traffic on the wired LAN. Video traffic is RTP traffic consisting of video data and associated RTCP traffic.This setting is available only when you enable 802.1p/Q. You can use any value from 0 to 7, although Polycom recommends not using 6 and 7.

    Audio Priority

    Sets the link layer priority of audio traffic on the wired LAN. Audio traffic is RTP traffic consisting of audio data and associated RTCP traffic. This setting is available only when you enable 802.1p/Q. You can use any value from 0 to 7, although Polycom recommends not using 6 and 7.

    Control Priority
    Sets the link layer priority of control traffic on the wired LAN. Control traffic consists of control information associated with a call:
    • H.323: H.225.0 Call Signaling, H.225.0 RAS, H.245, Far-End Camera Control (FECC)
    • SIP: SIP Signaling, FECC, Binary Floor Control Protocol (BFCP)

    This setting is available only when you enable 802.1p/Q. You can use any value from 0 to 7, although Polycom recommends not using 6 and 7.
