Wildcard mask in ACL

[Anton_Visser]

I want to filter subnets with the same 3rd octet and different 2nd octet.
With Cisco i can use:
10.0.64.0 0.255.0.255
Is this also possible with EXOS?

Example:
seq 20 permit ip 10.0.64.0 0.255.0.255 any

I've moved this topic to the EXOS category and deleted the duplicate post there.

Anton,

For basic functionality, the CER/CES devices should cover normal network needs, however they are legacy devices and are approaching End of Life. This would be cost efficient, but supportability would be lacking.

For a long term solution, you could look into the SLX platform, we have an array of different variants of these boxes that may address your needs.

I would highly recommend you call into sales to discuss as I am only familiar with the SRA products we provide, there are many other solutions we may be able to offer.

Thanks,

Hello Mike,
Thanks for your fast reply.
Is i read in the EXOS guides it is not possible so i was looking for an alternative.
Now i only need to select the best switch/router.
I do not need a high end router.
24x 1Gbit ports are enough.
Any suggestion?

Bye,
Anton.

Anton,

This discussion channel is primarily for SRA products, meaning NOS, NetIron, and SLX.

For these products, your understanding is correct. For example, the source-ip

10.157.22.26

and wildcard value

0.0.0.255

mean that all hosts in the Class C subnet 10.157.22.x match the policy. In your example you used:

10.0.64.0

0.255.0.255

This would match all hosts with 10.x.64.x.

For additional Details on ACL configuration, I would suggest you review the "Security Guides" found on our documentation site:

NetIron Security Guide

NetworkOK Security Guide

SLX Security Guide

If your question pertains to the Legacy Extreme OS, I would recommend you move your post to that discussion channel.

I hope this helps,
