UNP and Policy list

Post by RvW »

Does anyone have some good information on how to implement a Policy List for a UNP?

I have setup the following Policy List:

policy condition Any source ip Any destination ip Any
policy action Accept
policy action Deny disposition deny
policy rule DenyAll condition Any action Deny no default-list
policy rule AllowAll condition Any action Accept no default-list
policy list QUARANTINE type unp rules DenyAll
qos apply

And defined the following UNP

Max Max Max
Role Name Vlan HIC Policy List Name Ingress-BW Egress-BW Default-Depth Redirect URL
--------------------------------+----+----+-------------------------------+----------+----------+---------------+------------
QUARANTINE 20 No QUARANTINE - - - -

The UNP is pushed down from ClearPass:

sw01-> show aaa-device all-users

Slot MAC User Addr IP Authentication User Network Policy List
Port Address Name Vlan Mode Address Type Result Profile Name Name
-----+-----------------+---------------+----+----+---------------+----+----+------------------+-------------------------------
1/4 b8:27:eb:48:fe:e1 B827EB48FEE1 20 Brdg 192.168.20.199 MAC Pass QUARANTINE QUARANTINE

Despite the DenyAll rule the device still gets an IP address. I have tried various other conditions and it doesn't look like any is applied. Some show commands, such as show active policy rule, seem to be geared to the Default Policy List only and not show anything in this case.

If anyone has successfully done this, it would be great to see some examples. Running 6.7.2 R07.

Is other traffic (beside getting an ip) possible from this clientß
Please provide "show configurations snapshot aaa".
You can check matching policy lists with "show active policy list".
Despite the dhcp discover have an ip address (so your rule should match) it will be good to use a specific rule with udp destination port 67.
Also you can try to change your condition to only "destination ip any".

It seems that with the DenyAll rule as per the previous communication it still gets an IP address, but any communications, other than ARP, after that is blocked. Even if I add a DHCP rule in, as per the below, it still gets an IP address (assuming the use of 'precedence' in a rule is correct, as show commands don't seem to take the 'precendence' into account and list rules alphabetically).

sw01-> show configuration snapshot aaa

with your correct config (no default-list) only the traffic from the clients associated with the unp QUARANTINE (checked with show aaa-device all-users) should use the rules DenyAll and DenyDHCP (independing of the precedence). So you can use very easy and very common conditions "like destination ip any" or "source vlan 20" to cover all traffic.
So there has to be a way forbit dhcp too. Also you can add keyword "log" to your rule. so you can check with "show qos log" the matched packets.
best regards
