Configuring Gns Filters - Alcatel-Lucent OmniSwitch 6850-48 Network Configuration Manual

Configuring IPX
You can narrow the filter by specifying a VLAN and a SAP type. For example, to create a filter that will
block 0004 (NetWare File Server) SAP updates from being sent to VLAN 1 you would enter:
-> ipx filter 1 sap 0004 out block
You can also narrow the filter by specifying a network. You must enter the network number and the
network mask. For example, to create a filter that will block 0004 SAP updates from being sent to network
222 and its subnets you would enter:
-> ipx filter sap 0004 out block 222 mask ffffffff
Use the no ipx sap filter command to delete a SAP filter. For example, to delete a global SAP filter that
was configured to block incoming SAP packets you would enter:
-> no ipx filter sap in block
Use the optional syntax to delete a filter for a specific VLAN or network. If you are deleting the filter for a
specific network, you can also enter the network mask. To delete a filter from all VLANs/networks, use
only the basic command syntax (e.g., no ipx filter sap in allow).
Use the show ipx filter command to display all IPX filters.

Configuring GNS Filters

GNS output filters control which servers are included in the GNS responses sent by the switch. GNS
supports output filters only.
Use the ipx filter gns
to all traffic, enter the command, specify the GNS packet type to be filtered (all – all GNS packets or a
specific 4-digit hex GNS type), specify whether it is an input (in) or output (out) filter, then specify
whether you want the filter to allow or block traffic. For example, to block all GNS updates you would
enter:
-> ipx filter gns all out block
You can narrow the filter by specifying a VLAN. For example to block all GNS updates sent to VLAN 1
you would enter:
-> ipx filter 1 gns all out block
You can also narrow the filter by specifying a network. You must enter the network number and the
network mask. For example, to create a filter that will block updates sent to network 222 and its subnets
you would enter:
-> ipx filter gns all out block 222 mask ffffffff
Use the no ipx gns filter command to delete a GNS filter. For example, to delete a global GNS filter that
was configured to block all GNS updates you would enter:
-> no ipx filter gns all out block
Use the show ipx filter command to display all IPX filters.
