QoS and Firewall Rules 
By default, six  rules are preconfigured in the Meru Wireless LAN System. To update rule information, click Refresh. The following table lists the QoS and Firewall Rule information you can review. 
ID 
Unique numeric identifier for the QoS rule 
Destination IP 
Destination IP address, in conjunction with a destination subnet mask, used as criteria for matching the QoS rule 
Destination Netmask 
Subnet mask for the destination IP address 
Destination Port 
Destination TCP or UDP port used as criteria for matching the QoS rule (zero specifies any port) 
Source IP 
Source IP address, in conjunction with a destination subnet mask, used as criteria for matching the QoS rule 
Source Netmask 
Subnet mask of the source IP address 
Source Port 
Source TCP or UDP port used as criteria for matching the QoS rule (zero specifies any port) 
Network Protocol 
Network protocol: Determines whether the flow is TCP or UDP 
17=UDP 
6=TCP 
If you are using a QoS protocol detector, you must match the network protocol with the type of QoS protocol: 
UDP: SIP 
TCP: H.323 
TCP: SCCP 
Firewall Filter ID 
Specifies the filter-ID in use (per-user or per-ESS), if Per-User Firewall configuration is enabled (optional feature). This ID must be between 1 and 16 characters. 
Packet Minimum Length 
Size of the minimum packet length needed to match the rule. 
Packet Maximum Length 
Size of the maximum packet length needed to match the rule. 
QoS Protocol 
SIP 
H.323 
SCCP 
Other 
Action 
Specifies what the rule does with packets: 
Forward: A flow is given an explicit resource request, bypassing the QoS protocol detector and regardless of whether a QoS protocol was specified. 
Capture: The system, using a QoS protocol detector, analyzes the flow for its resource requirements. 
Drop: The flow is dropped. 
Drop Policy 
Identifies what happens to packets that arrive when the queue is full: 
Head: New packets that arrive after the queue has reached its maximum length are allowed in the queue, and old information in the queue is replaced with the new information. 
Tail: New packets that arrive after the queue has reached its maximum length are dropped. 
QoS Rule Logging 
Specifies whether QoS rule activity logging is off or on. If on, packets that match this rule are logged. If off, packets are not logged. 
QoS Rule Logging Frequency 
Specifies the logging interval in which packets related to this rule are updated,  if QoS Logging is enabled. The interval must be a number between 30 and 60 seconds.
