From the Orchestrator, go to Diagnostics > Remote Diagnostics > [Edge] > List Paths , and select Run to view the list of active paths.

• Network configuration files are located under /etc/netplan.

  Example network configuration (whitespace is important!)- /etc/netplan/50-cloud-init.yaml:

  network: version: 2 ethernets: eth0: addresses: - 192.168.151.253/24 gateway4: 192.168.151.1 nameservers: addresses: - 8.8.8.8 - 8.8.4.4 search: [] routes: - to: 192.168.0.0/16 via: 192.168.151.254 metric: 100 eth1: addresses: - 192.168.152.251/24 gateway4: 192.168.152.1 nameservers: addresses: - 8.8.8.8 search: []

echo 'network: {config: disabled}' > /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg

• The following example will configure access to all counters from localhost via community string vc-vcg and from 10.0.0.0/8 with community string myentprisecommunity using SNMPv2c version.

  agentAddress udp:161 # com2sec sec.name source community com2sec local localhost vc-vcg com2sec myenterprise 10.0.0.0/8 myentprisecommunity# group access.name sec.model sec.name group rogroup v2c local group rogroup v2c myenterpriseview all included .1 80 # access access.name context sec.model sec.level match read write notif access rogroup "" any noauth exact all none none#sysLocation Sitting on the Dock of the Bay #sysContact Me <このメールアドレスはスパムボットから保護されています。閲覧するにはJavaScriptを有効にする必要があります。>sysServices 72master agentx# # Process Monitoring ## At least one 'gwd' process proc gwd # At least one 'mgd' process proc mgd# # Disk Monitoring # # 100MBs required on root disk, 5% free on /var, 10% free on all other disks disk / 100000 disk /var 5% includeAllDisks 10%# # System Load # # Unacceptable 1-, 5-, and 15-minute load averages load 12 10 5 # "Pass-through" MIB extension command pass_persist .1.3.6.1.4.1.45346 /opt/vc/bin/snmpagent.py veloGateway

  Note: In the above example, the process gwd comprises entire Data and Control Plane of the Gateway. The Management Plane Daemon (mgd) is responsible for communication with the Orchestrator. This process is kept isolated from gwd so that in the incident of a total failure of the gwd process, the Orchestrator is still reachable for configuration changes or software updates required to resolve the failure.
• The following example shows configuration using SNMPv3 version.
