Fix Recommendation

This requirement is not applicable for the DODIN Backbone.

Configure the perimeter router of the managed network with an ACL or filter on the egress interface to block all outbound management traffic.

Configure an ACL to block egress management traffic, as shown in the example below:

ICX(config)#ip access-list extended EXTERNAL_ACL_OUTBOUND
ICX(config-ext-ipacl-EXTERNAL_ACL_OUTBOUND)#deny tcp any any eq radius log
ICX(config-ext-ipacl-EXTERNAL_ACL_OUTBOUND)#deny tcp any any eq sshow log
ICX(config-ext-ipacl-EXTERNAL_ACL_OUTBOUND)#deny udp any any eq snmp log
ICX(config-ext-ipacl-EXTERNAL_ACL_OUTBOUND)#deny udp any any eq syslog log
ICX(config-ext-ipacl-EXTERNAL_ACL_OUTBOUND)#deny ip any any log
ICX(config-ext-ipacl-EXTERNAL_ACL_OUTBOUND)#exit

Configure the external interfaces with the outbound ACL, as shown in the example below:

ICX(config)#interface ethernet x/x/x
ICX(Config-if-e10000-x/x/x)#ip access-group EXTERNAL_ACL_OUTBOUND out logging enable

Check Contents

This requirement is not applicable for the DODIN Backbone.

The perimeter router of the managed network must be configured with an access control list (ACL) or filter on the egress interface to block all management traffic.

Verify all external interfaces have been configured with an outbound ACL as shown in the example below:

EXTERNAL_ACL_OUTBOUND: 5 entries
10: deny tcp any any eq radius
20: deny tcp any any eq sshow log
30: deny tcp any any eq snmp log
40: deny udp any any eq syslog log
50: deny ip any any log

interface ethernet x/x/x
ip access-group EXTERNAL_ACL_OUTBOUND out logging enable

If management traffic is not blocked at the perimeter, this is a finding.
