Chapter 8 Basic Setting Table 17 Basic Setting > Port Setup (continued) LABEL BPDU Control Force Agent Information Apply Cancel DESCRIPTION Configure the way to treat BPDUs (Bridge Protocol Data Units) received on this port. You must activate bridging control protocol transparency in the Switch Setup screen first. Select Peer to look at the information in the received BPDUs. For example, the root bridge's existence, if any bridge was added or removed from the STP (Spanning Tree Protocol) network, if any loop occurred in the STP network. Select Tunnel to add the incoming port's PVID on the received BPDUs and then forward them to the next Switch. Select Discard to drop all BPDUs received on this port. Set this only on an edge port of a STP network. Select Network to forward VLAN-tagged BPDUs to the next Switch directly and handle VLANuntagged BPDUs as the Peer option. See Section 14.1.2 on page 161 for more information about BPDU. Select force to allow the Switch to add/replace a DHCP option 82 tag in the corresponding packets received by this port for the following applications: • PPPoE IA (See Section 32.4 on page 291 and Section 32.5 on page 293) • DHCP relay (See Section 35.4.4 on page 314) • DHCP VLAN (See Section 35.5 on page 318) • DHCP snooping (See Section 26.5.2 on page 260) Select transparent to ignore the PPPoE IA and DHCP option 82 tag settings of packets received on this port. Click Apply to save your changes to the Switch's run-time memory. The Switch loses these changes if it is turned off or loses power, so use the Save link on the top navigation panel to save your changes to the non-volatile memory when you are done configuring. Click Cancel to begin configuring this screen afresh. 8.10 Rate Limit Profile Setup Rate limit profiles define ingress and egress data rate limits for the Switch port(s). Click Basic Setting and Rate Limit Profile Setup in the navigation panel to display the screen as shown. Figure 42 Rate Limit Profile Setup 84 VES1724-56 User's Guide
