Configuring network settings

To configure the network settings on the IP VCR and check the network status, go to Network > Port A or Network > Port B.

The IP VCR has two Ethernet interfaces, Port A and Port B. The configuration pages for the two interfaces look and behave similarly, and therefore are described together. Differences are noted as appropriate.

Port A can be configured to be allocated its IP address by DHCP. Port B cannot use DHCP. Connect Port A to your local network and connect Port B to a second subnet or the internet depending on your application of the IP VCR.

On this page:

IP configuration settings

These settings determine the IP configuration for the appropriate Ethernet port of the IP VCR. When you have finished, click Update IP configuration and then reboot the IP VCR.

 

Field Field description Usage tips
IPv4 configuration
IP configuration

Specifies whether the port should be configured manually or automatically. If set to Automatic via DHCP the IP VCR obtains its own IP address for this port automatically via DHCP (Dynamic Host Configuration Protocol). If set to Manual the IP VCR will use the values that you specify in the Manual configuration fields below.

Click Renew DHCP to request a new IP address if you have selected automatic configuration.

Port A should never be disabled because it is the primary interface of the IP VCR.

Manual configuration
IP address

The dot-separated IPv4 address for this port, for example 192.168.4.45.

You only need to specify this option if you have chosen Manual IP configuration, as described above.

For Port A, if the IP configuration setting is set to Automatic by DHCP this setting is ignored.

Subnet mask

The subnet mask required for the IP address you want to use, for example 255.255.255.0

 

Default gateway

The IP address of the default gateway on this subnet, for example 192.168.4.1

 

DNS configuration
Host name

Specifies a name for the IP VCR.

Depending on your network configuration, you may be able to use this host name to communicate with the IP VCR, without needing to know its IP address.

DNS configuration

Specifies whether DNS should be configured manually or automatically. If set to Manual the IP VCR will use the values that you specify in the three configuration fields below.

 

Name server

The IP address of the name server.

 

Secondary name server

Identifies an optional second name server.

The secondary DNS server is only used if the first is unavailable. If the first returns that it does not know an address, the secondary DNS server will not be queried.

Domain name (DNS suffix)

Specifies an optional suffix to add when performing DNS lookups.

This can allow you to use non-fully qualified host names when referring to a device by host name instead of IP address.

For example, if the domain name is set to cisco.com, then a request to the name server to look up the IP address of host endpoint will actually lookup endpoint.cisco.com.

IP status

Use the IP status fields to verify the current IP settings for the appropriate Ethernet port of the IP VCR, which were obtained using DHCP or configured manually (see IP configuration settings) including:

Ethernet configuration

These settings determine the Ethernet settings for the appropriate port of the IP VCR. Refer to the table for assistance with these settings. When you have finished, click Update Ethernet configuration.

 

Field Field description Usage tips
Ethernet settings

Specify whether you want this Ethernet port to automatically negotiate its Ethernet settings with the device it is connected to, or if it should use the values that you specify in the Manual configuration fields below.

It is important that your Ethernet settings match those of the device to which this port is connected. For example, both devices must be configured to use automatic negotiation, or both configured with fixed and matching speed and duplex settings (see below).

Manual configuration
Speed

Identifies the connection speed: 10 Mbit/s or 100 Mbit/s. Use automatic negotiation if a connection speed of 1000 Mbit/s is required.

The connection speed must match that of the device to which this port is connected.

You only need to select this option if you have chosen Manual Ethernet settings, as described above.

Duplex

Identifies the connection duplex mode:

  • Full duplex
    Both devices can send data to each other at the same time
  • Half duplex
    Only one device can send to the other at a time

The duplex setting must match that of the device to which this port is connected.

You only need to select this option if you have chosen Manual Ethernet settings, as described above.

Ethernet status

Field Field description Usage tips
Link status

Indicates whether this Ethernet port is connected to or disconnected from the network.

 

Speed

The speed (10/100/1000 Mbit/s) of the network connection to the IP VCR on this port.

This value is negotiated with the device to which this port is connected or based on your Manual configuration selected above.

Duplex

The duplex mode (Full duplex or Half duplex) of the network connection to this port.

This value is negotiated with the device to which this port is connected or based on your Manual configuration selected above.

MAC address

The fixed hardware MAC (Media Access Control) address of this port.

This value cannot be changed and is for information only.

Packets sent

Displays a count of the total number of packets sent from this port by the IP VCR. This includes all TCP and UDP traffic.

When troubleshooting connectivity issues, this information can help you confirm that the IP VCR is transmitting packets into the network.

Packets received

Displays a count of the total number of packets received by this port of the IP VCR. This includes all TCP and UDP traffic.

When troubleshooting connectivity issues, this information can help you confirm that the IP VCR is receiving packets from the network.

Statistics:

These fields display further statistics for this port.

  • Multicast packets sent
  • Multicast packets received
  • Total bytes sent
  • Total bytes received
  • Receive queue drops
  • Collisions
  • Transmit errors
  • Receive errors

Use these fields for advanced network diagnostics, such as resolution of problems with Ethernet link speed and duplex negotiation.
