+Embedded Lab 1
+==============
+
+This lab is currently located in Oakland, CA.
+
+Due to limitations, there is no static IPv4 address allocated for the
+lab controller.  Access is through either port forwarding or an HTTPS
+proxy to access it.  It will have static IPv6 addresses for use.
+
+Hardware
+--------
+
+The PoE switch used is the Netgear GS724TPv2.  The firmware used is
+v1.1.50.39.  The original firmware, v1.1.1.25, did not support the standard
+PoE SNMP MIB (RFC 3621).
+
+There is a bug, [issue #194](https://github.com/net-snmp/net-snmp/issues/194),
+in net-snmp which requires using a timeout of 2 seconds for the snmpset
+command to complete successfully.  If the default timeout is used, the
+commands will execute, but net-snmp will report a timeout error.
