Service Creation Using Groups and Rules
TUT Systems, Inc Page 68 of 104 P/N 220-06288-20
Using Rule Priorities
Each rule has a numeric priority; the smaller the number, the greater the priority. When
assigning a group to a new session, the SMS2000 first looks at all rules with priority 1. If
it finds any matching rule, it stops and uses the group for that rule. If it does not find any
matching rule, it goes on to rules with priority 2, and so on.
Managers can use multiple rules in conjunction with one another to provide unique
service offerings. For example, a manager has a client named Geraldo in an MCU setting.
He is connected through an MDU Lite on port 1. He has a web server at ip
123.123.123.5, and an e-mail server at 123.123.123.6, both of which require a static IP
address with no authentication. He also has 13 employees, each of whom is running a PC
with DHCP, and would like to have them receive a real IP address.
The manager can enter the following commands:
SMS2000% group add gerstat
Active group is “gerstat”
SMS2000% auth off
SMS2000% iptype static
SMS2000% set rule gerstat5 1 ip=123.123.123.5 and
snmp-info=123.123.123.123-001-001
SMS2000% set rule gerstat6 1 ip=123.123.123.6 and
snmp-info=123.123.123.123-001-001
SMS2000% group *
Active group is “*”
SMS2000% group add gerdhcp
Active group is “gerdhcp”
SMS2000% auth off
SMS2000% dhcp-pool gerpool 123.123.123.7 123.123.123.20
255.255.255.0
SMS2000% iptype DHCP
SMS2000% set rule gerdhcp 2 snmp-info=123.123.123.123-001-001
Any device that connected through 123.123.123.123-001-001 matches the “gerdhcp”
rule.
However, since that rule has a priority 2, which is lower than both “gerstat5” and
“gerstat6,” those other rules will be checked first. Since both Geraldo’s web server and e-
mail server have an IP in one of those rules, they will be placed in the “gerstat” group,
which has a more restrictive membership, but allows devices to have a static IP.
