Signaling Security Templates
Creating a template
Signaling Security templates define rules for calls screening based on the call's
source/destination addresses.
A template holds the following information:
1 Name of template - up to 20 characters template name.
2 Source NSAP/Mask - A specific NSAP address or an address mask.
3 Destination NSAP/Mask - A specific NSAP address or an address mask.
4 The rule - deny or permit.
An address mask is an expression designed to define a set of addresses. A mask
expression may include two wildcards characters '*' and '?' where '*' represents any
address portion (i.e. any number of nibbles) and '?' represents a single nibble (half a
byte).
Example: an address mask that is designed to match an ATM host having a MAC
address of 11.22.33.44.55.66 (i.e. bytes 14-19are the MAC) would have the form of:
*.11.22.33.44.55.66.??, where the '*' represents the ATM prefix, and the '??' represents
the Selector.
Example: an address mask that is designed to match all the hosts having an address
prefix 39.03.00.00.00.00.00.00.00.00.00.00.00 would have the form of
39.03.00.00.00.00.00.00.00.00.00.00.00.*
Where the '*' represents all possible combinations for ESI + Selector.
Creating a template:
Command: M15-155s8:/> vport sig sigsecurity template create <name>
[srcnsap <mask>] [dstnsap <mask>] <action>
Example: M15-155s8:/>vport sig sigsecurity template create block-
r&d srcnsap 39.03.00.00.00.* dstnsap * deny
Parameters <name> name of the template
<mask> source/destination address masks
<action> “deny” - to reject the call
