Creating Distributed Key Policies

Table 49		Mesh policy entries
	Field		Description
	Name		Enter a unique name to identify the policy. Names can be 1 - 40 characters in
			length. Alphanumeric characters and spaces are valid. The special characters
			<, >, &, “ *, ?, /, \, : and cannot be used in the policy name. Names are not
			case sensitive.
	Priority		Enter the priority for this policy from 1 to 65000. PEPs enforce policies in
			descending priority order with the highest priority number processed first.
	Renew Keys/		Specifies the lifetime of the keys and policies, and the frequency at which the
	Refresh		keys are regenerated and policies’ lifetimes are updated on the PEPs.
	Lifetime		Regenerate keys and update policies either at a specified interval in hours or
			daily at a specified time. Click either Hours or Daily.
			• Hours - enter the re-key interval in hours between 0 and 65535 hours. 0
			hours causes keys and policies to never expire and never update. Use 0
			hours for drop and clear policy types.
			• Daily at - enter the re-key time using the 24 hour system clock set to the
			required local time of the ETPM workstation. The re-key time will translate to
			the local times of the ETKMSs and PEPs that might be located in other time
			zones.
	Type		Specifies the action applied to packets that match the protocol and networks
			included in this policy.
			• Drop - drops all packets matching this policy.
			• Bypass - passes all packets matching this policy in the clear.
			• IPSec - encrypts or decrypts all packets matching this policy.
	IPSec		Specifies the encryption and authentication algorithms used in an IPSec policy.
			Select the encryption algorithm from the Encryption Algorithms list:
			• AES - Advanced Encryption Standard (default)
			• 3DES - a more secure variant of Data Encryption Standard
			Select the authentication algorithm from the Authentication Algorithms list:
			• HMAC-SHA-1- Secure Hash Algorithm
			• HMAC-MD5- Message Digest 5
			Note: Layer 4 policies require AES and HMAC-SHA-1.
	Key Generation		Specifies the key generation and distribution mechanism for the PEPs included
			in this policy.
			• By Network Set - The default ETKMS within each network set generates
			and distributes the keys to the PEPs included in those network sets.
			• Global ETKMS - A global ETKMS generates the keys and sends them to
			the default ETKMSs in each network set for distribution to all of PEPs
			included in the policy.
			Select the desired ETKMS from the Global ETKMS list.
