Restricting Client-To-Client Forwarding Among IP-Only Clients 409

 

Setting 802.11b/g Radios to 802.11b (for Siemens SpectraLink VoIP

 

Phones only)

 

If you plan to use Siemens SpectraLink Voice over IP (VoIP) phones, you

 

must change the MAP radios that will support the phones to operate in

 

802.11b mode only. This type of phone expects the MAP to operate at

 

802.11b rates only, not at 802.11g rates. To change a radio to support

 

802.11b mode only, use the radiotype 11b option with the set ap

 

command.

 

Disabling RF Auto-Tuning Before Upgrading a SpectraLink Phone

 

If you plan to upgrade a SpectraLink phone using TFTP over a MAP, 3Com

 

recommends that you disable RF Auto-Tuning before you begin the

 

upgrade. This feature can increase the length of time required for the

 

upgrade. You can disable RF Auto-Tuning on a radio-profile basis. Use the

 

following commands:

 

set radio-profile name auto-tune channel-config disable

 

set radio-profile name auto-tune power-config disable

 

 

Restricting

You can use an ACL to restrict clients in a VLAN from communicating

Client-To-Client

directly at the IP layer. Configure an ACL that has ACEs to permit traffic to

Forwarding Among

and from the router (gateway), an ACE that denies traffic between all

IP-Only Clients

other addresses within the subnets, and another ACE that allows traffic

 

that doesn’t match the other ACEs.

 

AN ACL can restrict IP forwarding but not Layer 2 forwarding. To restrict

 

Layer 2 forwarding, see “Restricting Layer 2 Forwarding Among Clients”

 

on page 94.

 

For example, to restrict client-to-client forwarding within subnet

 

10.10.11.0/24 in VLAN vlan-1with router 10.10.11.8, perform the

 

following steps:

1Configure an ACE that permits all traffic from the gateway IP address to any other IP address:

WX1200# set security acl ip c2c permit 10.10.11.8 0.0.0.0

2Configure an ACE that permits traffic from any IP address to the router IP address:

WX1200# set security acl ip c2c permit ip 0.0.0.0 255.255.255.255 10.10.11.8 0.0.0.0
