1.13 System Log
/var/log/message keeps a circular log in memory, no filesystem activity involved.
1.13.1 Enabling System Logging
To read the logfile from syslogd you should use the logread command, which outputs the messages in
syslogd's circular buffer.
Logging is always enabled.
1.14 DHCP Configuration
The SR1410 can be configured as a controller less Mesh Point Portal [MPP] or a controller based Mesh
Point [MP]. When configured as MPP, the DHCP addresses are allocated by the node itself. The DHCP
Directives in the main configuration screen drive the behavior of the mesh node.
Normally, the dhcp server running on the network manager serves all the clients connecting to the nodes
within a mesh block.
The dhcp server needs to be aware of the subnets at the mesh node access points and be able to assign
dynamic addresses based on those subnets.
The dhcp server shall assign a common dns server to all the clients within the mesh block.
The dhcp server shall be aware of the mesh node access point IP address from which the dhcp lease
request is received for a client. This AP address is the default router which shall be assigned to the client
requesting dhcp lease.
The Mesh block network topology comprises several nodes and each node may have an AP within a
subnet different from that of the DHCP interface. It is therefore necessary that the DHCP server detect
the subnet of the AP from which the DHCP request was originally received on behalf of a client. Once it
has the subnet information of this AP, it should assign the requesting client an IP address within the
same subnet as the AP.
The SR1410 can also be operated an MP where it relies on the network manager to allocate DHCP
addresses. On the other hand, it can also act as a DHCP server for a cluster of MPs. The node that is
elected to run DHCP service is the MPP.
