This command configures the network settings.

Syntax

(config-network)# network-settings
(network-settings)#

Command

Description

aws-ec2-endpoint

Defines the Amazon Web Services (AWS) EC2 endpoint name:

■

Empty (default): The device automatically generates the AWS EC2 API endpoint based on the region in which it is deployed (e.g., "ec2.eu-central-1.amazonaws.com").

Note: High-Availability (HA) deployments in AWS environments use AWS EC2 API to implement IP failover. If two SBC instances are deployed in separate availability zones within the same region, the same AWS EC2 API endpoint will be used for both availability zones. In such a scenario, all traffic towards the AWS EC2 API endpoint will flow through the first availability zone, even for virtual machines deployed in the second availability zone.

■

Custom EC2 API endpoint FQDN (e.g., "vpce-0123456789.ec2.eu-central-1.vpce.amazonaws.com").

■

Custom EC2 API endpoint FQDN followed by its IP address (e.g., "ec2.eu-central-1.amazonaws.com:10.1.2.3").

Note: The parameter is applicable only to Mediant VE/CE in AWS environments.

dns-cache {disable|enable}

Enables the device to cache (store) DNS-resolved IP addresses of the last successful DNS query of Proxy Sets configured with an FQDN.

ethernet-redundancy {auto|disable|enable}

Enables Ethernet port redundancy, configured in the Ethernet Groups table.

Note: The parameter is applicable only to Mediant 90xx and Mediant Software.

hostname

Defines the device's hostname.

icmp-disable-redirect {0|1}

Enables sending and receiving of ICMP Redirect messages.

icmp-disable-unreachable {0|1}

Enables sending of ICMP Unreachable messages.

interface-status-check {0|1}

When the device is deployed in Azure cloud, it may experience intermittent problems in communication with virtual hosts that may cause the virtual network interface (NIC) to "freeze". To overcome this issue, the device can periodically check the status of all network interfaces to detect if this condition exists and mitigate it by performing a maintenance reboot.

Note: The parameter is applicable only to Mediant VE/CE deployed on the Azure cloud platform.

limit-incoming-icmp-echo-requests

Defines if the device limits the number of allowed incoming ICMP echo requests.

Note: The parameter is applicable only to Mediant 90xx and Mediant Software.

osn-internal-vlan {off|on}

Enables a single management platform when the device is deployed as a Survivable Branch Appliance (SBA) in a Microsoft Skype for Business environment. It allows configuration and monitoring of the Gateway/SBC device through the SBA Management Interface.
