XL-HB14128M HomePNA3.0 Switch User’s Guide
can be forwarded to the correct destined HomePNA port. Terminals attached on port 1 to port 14 should be able to
receive tagged/untagged packet and can transmit tagged/untagged packet.
NOTE:
The
connection may be terminated abnormally while Tag VLAN is being turned on and the terminal (PC) can't
recognize/receive tagged packets, especially while you configure the VID/Priority setting on port E1.
Egress Action Rules
‘Action’ will take effect while packets outgoing from each port of XL-HB14128M,
1. Tag: Untagged packets will be tagged with each default VID and Priority when they go out.
2. UnTag: Tagged packets will be forced to get rid of Tag, become untagged packet when they go out.
3. Pass: Either tagged or untagged packets pass through unchanged.
SNMP
SNMP
Agent
inside XL-HB14128M will handle request from
SNMP
Manager
. The agent supports standard SNMP
operations as ‘SET’, ‘GET’ and ‘TRAP’.
XL-HB14128M SNMP is setting to read-only mode by default. You need to specify the
Read/Write Community
Name
into switch before any SNMP ‘SET’ operation can work. Default setting will only allow agent to monitor the
switch and report the requested SNMP data to SNMP manager.
You may need the accompanying proprietary
MIB file
for some popular SNMP/MIB manager software to manage the
switch system. Or to integrate the XL-HB14128M switch system into your original SNMP management system by this
specific MIB file.
Each SNMP manager must indicate the name of the community it belongs in all ‘GET’, ‘SET’ and ‘TRAP’ operations.
The community name could be unique to allow set of SNMP managers to access to the agent. The default ‘GET’ and
‘TRAP’ community name of XL-HB14128M is ‘
public
’.
Rate Control
You may impose the restriction of maximum available data rate on HomePNA port for either upstream or downstream
traffic. Rate control disabled by default, and each port could have the maximum possible data rate.
QoS
Quality of Service is enforced by assigning each incoming packet with a predefined priority value. Packet with higher
priority should be processed as soon as possible (fast in, fast out). In shortage of buffers, some low priority packets
should be discarded to smooth the high priority traffic flow. Higher priority traffic will have higher data rate and lower
possibility of discarding.
The numbering priority value ranges from 0 to 7, and 7 represents the highest priority level. XL-HB14128M supports
priority scheme as Port-Based, 802.1P, IP TOS and TCP/UDP protocol.
Priority in Downstream
There are 4 priority queues for upstream packet. Packet with priority value 0 or 1 goes to the same queue, denoted as
Q0. Q1 has priority value 2 and 3, Q2 has priority value 4 and 5, and Q3 has priority value 6 and 7. Totally 4 level of
service are provided. Q3 will always be the first one to service, i.e. packets reside in Q3 will be send out first. Packets
in Q0 will be discarded first in congestion situation since it is classified as less important.
