Watson 5 Ethernet
Operating Manual
Revision: 2006-04-27 3-17
Each combination of rates is associated with a profile number. This profile number is used in the
RATELIMIT IN Monitor command to configure a particular combination of rates.
After classification and rate limiting the packets are sent to their output queues. A scheduler will
schedule packets according to their priorities and send them to the egress port. The scheduler can
be configured to work either in strict priority mode or in weighted fair queuing mode with fixed
weights 8:4:2:1 for Q4:Q3:Q2:Q1 respectively.
Scheduling policy is a global setting and affects all ports simultaneously.
Finally the egress port can be rate limited according to the following profiles:
Profile Rate
8
23.5M
7
11.8M
6
5.9M
5
2.9M
4
1.5M
3
734.4k
2
367.2k
Table 3-5: Egress rate limiter profiles
The profile number is used in the RATELIMIT OUT command to configure a particular egress
rate. Only the entire port after scheduling can be rate limited, there are no individual queues at this
stage.
Note: CoS functions are not available on the Watson 5 Ethernet tabletop modems.
3.3 Ethernet (tabletop modem)
3.3.1 Ethernet over DSL
The Watson 5 Ethernet tabletop modem uses the same HDLC procedure to transport Ethernet
frames over DSL as the Watson 5 Ethernet plugin modem. Cf. 3.2.1
3.3.2 VLAN transparency
The Watson 5 Ethernet tabletop modem is transparent for VLAN tags according to IEEE 802.1p/q.
This means that all Ethernet packets regardless whether they have a VLAN tag or not are handled
correctly by Watson 5 Ethernet. However the filtering bridge of Watson 5 Ethernet is not VLAN
aware. This means that packet forwarding and MAC address learning is performed without taking
the VLAN tag into account.
