Setting Up Quality of Service
Configuring LLQ
Network 1 at Site A, shown in Figure 8-6, contains VoIP equipment that
communicates with equipment at Network 4 at Site B. Host 26 on Network 1
is an email server; it does not send real-time data. To select the traffic to be
placed in a low-latency queue, enter:
ProCurve(config)# ip access-list extended LowLatencyTraffic
ProCurve(config-ext-nacl)# deny ip host 172.16.1.26 any
ProCurve(config-ext-nacl)# permit ip 172.16.1.0 0.0.0.255 172.16.4.0 0.0.0.255
You can also select certain types of traffic (for example, HTTP or Telnet) by
specifying a protocol such as TCP or UDP and then indicating the source or
destination port after the address:
Syntax: [deny | permit] <protocol> [any | host <A.B.C.D> | <A.B.C.D> <wildcard bits>]
[any | eq <port> | gt <port> | lt <port> | range <first port> <last port> | neq <port> | host
<port>] [any | host <A.B.C.D> | <A.B.C.D> <wildcard bits>] [any | eq <port> | gt <port>
| lt <port> | range <first port> <last port> | neq <port> | host <port>]
For example:
ProCurve(config-ext-nacl)# permit tcp host 172.16.1.30 eq telnet any
The eq keyword selects a single port and the range keyword allows you to
enter a range of ports. For more information about configuring ACLs, see
Chapter 5: Applying Access Control to Router Interfaces.
Matching a QoS Map Entry to an ACL. Move to the configuration mode
context for the QoS map entry you have created. Then enter this command:
Syntax: match list <ACL listname>
For example:
ProCurve(config-qos-map)# match list LowLatencyTraffic
Placing Bridged Traffic in a Low-Latency Queue. You can configure one
or more interfaces on a the ProCurve Secure Router to act as a bridge. In effect,
the router extends a LAN throughout two or more remote sites. Traffic
between hosts at each local site can obviously travel faster than that between
hosts at different sites. Local hosts are not only physically closer, but they can
also take advantage of higher-speed Ethernet connections.
