Defining a T1/E1 Management Channel 159Models 2616RC, 3096RC & 3196RC Admin Reference Guide 11 • In-band managementStatus. Once LCP has finished the negotiation of the configuration values, the link is in the UP state. Butfor data transfer to occur, the Network Control Protocol (NCP) must be established. In this example, theNCP is IPCP. The two possible states are:– DOWN, meaning the link is not yet in the UP state. (The UP state is typically reached upon completionof the LCP, Authorization/LQM phases. In this instance, there is no Authorization/LQM phase.)– UP, meaning the link is in the UP state. It may or may not have established the NCP. NCP must beestablished for data transfer over a PPP link.To change any of these three parameters—Slot, IP Address, or IP Mask—click on the Modify ManagementChannels… hyperlink (see figure 91 on page 158).5. A Gateway route must now be added, see chapter 12, “IP (IP, TCP, UDP, & ICMP)” on page 179 fordetails. The gateway IP address is the IP address of the device at the remote end of the T1/E1 PPP manage-ment channel.Deleting the T1/E1 management channel1. If you need to change the parameters for the T1/E1 management channel, you must first delete it and cre-ate a new one by clicking on T1/E1 in the Interface Type column. The WAN Circuit CONFIGURATIONLINK: 2 page displays.2. Click on the Channel Assignment… hyperlink, change all of the PPP timeslots for this management chan-nel to Clear, and click on Submit Query.3. Go back to the In-Band Management Overview to verify that the T1/E1 management channel hasbeen deleted.Example 3: T1/E1 Bridged PPP Management ChannelDo the following to create a bridged PPP (BCP) channel on T1/E1 port #3, timeslots 1-6.1. Set the parameters as follows:– Port: port3(3)– Function: ppp(5)– Timeslots: 1-62. Click on the Define button.3. Since you are configuring the T1/E1 port for PPP, the timeslots will automatically be set to PPP, even if thetimeslots were previously configured for clear or FrameRelay.4. In the Protocol Type column, you will see ppp-ipcp(1) which is the default protocol. For this bridged appli-cation, you must change the protocol type and the IP address of the management channel. ppp-bcp(2) isfor bridged routed PPP channels over the T1/E1 link. Change the Protocol Type by clicking the ModifyManagement Channels… link; the ppp-ipcp(1) link; the 192.168.200.1 link; and the Modify… link. ThePPP Link Configuration page displays.5. Change the PPP Protocol to ppp-bcp(2).6. The other displayed parameters are IP Address, IP Mask, and Status.
