Viewing the DHCP Relay Tab (AP) Using Informational Tabs in the GUI
Attribute Meaning
Ethernet Out Discards This field represents the number of packets tossed due to an
Ethernet out overload. This stat should never climb in normal
operation because the Ethernet link is much higher capacity than
the RF link. If this stat is incrementing, then either the Ethernet
link is established at a low speed (i.e. 10Mbps half duplex), or
there is a problem with cabling/Ethernet hardware.
RF In Discards This field indicates the number of packets tossed due to no
resources available within the radio to process them. This stat
also should never be increasing because the system is designed to
shed packets on the RF Out interface. If this stat is incrementing
the board is most likely congested due to high PPS rate in
combination with an Ethernet Out problem which will limit
packet flow off the device.
RF Out Discards This field indicates the number of packets tossed due to RF link
at capacity. This stat will increase whenever the RF link is at
capacity. When the internal FPGA RF input queue overflows,
this stat is incremented. If this stat is seen to be incrementing at
the AP, then the sector is congested. If seen at the SM, the
number of control slots should be looked at to ensure that enough
control slots are allocated to allow for bandwidth requests to be
seen at the AP.
Viewing the DHCP Relay Tab (AP)
The DHCP Relay statistics tab displays requests and replies received, relayed, and discarded when
the AP is configured as a DHCP relay. Typically, in a working DHCP realy configuration a one-
to-one ratio is established between requests and replies that are received and relayed.
