Enabling the Ethernet Access of an NE

Publication Date:  2012-07-25 Views:  60 Downloads:  0
Issue Description
In the NE Explorer select the NE, and then choose Communication > Access Control > Ethernet Access Control from the Function Tree. After disabling the Ethernet access of the NE, you cannot log in to the NE through the T2000 or Navigator that connects to the NE.
Alarm Information
Null.
Handling Process

To enable the Ethernet access, you can do as follows:

1. If the normal optical supervisory channel (OSC) or electrical supervisory channel (ESC) exists between an NE with the Ethernet access enabled and an NE with the Ethernet access disabled, you can log in to the NE with the Ethernet access disabled through the NE with the Ethernet access enabled. Select the NE with the Ethernet access disabled, and then choose Communication > Access Control from the Function Tree. In the Access Control area, select the Enabled check box, and then click Apply

2. If the NE with the Ethernet access disabled is an isolated NE or it connects to other NEs only through the extended ECC without OSC or ESC, you need to log in to the SCC board (the IP address of slot 17 is 192.168.0.250 and that of slot 18 is 192.168.0.251) of the NE in Telnet mode through the internal ETH1, ETH2, or ETH3 port. Then perform the following operations:

Step 1: Run the following command:

liulin=1

The following result is returned:

new symbol "liulin" added to symbol table.
liulin = 0x3fc6590: value = 1 = 0x1

Step 2: Run the following command:

dwDrvIoctl(3,4,0x3fc6590)

Step 3: Run the following command:

IF_GetIfByIndex(386)

The following result is returned:

value = 102472536 = 0x61b9b58

Step 4: Run the following command:

IF_LinkIOCtl(0x61b9b58,0,0)

The following result is returned:

value = 0 = 0x0

Step 5: On the Navigator, log in to the NE through the NE_ETH1 or NM_ETH2 port. Then run the following command to enable the Ethernet access of the NE:

:cm-set-lanaccess:0,open 
Root Cause
After the Ethernet access is disabled, the Ethernet access rights at the NM_ETH1 and NM_ETH2 ports are cancelled. As a result, the NE fails to be logged in through the two ports and the Ethernet access control cannot be enabled through the two ports. In addition, the Ethernet extended ECC function on the two ports fails.
Suggestions
Generally, do not disable the Ethernet access of an NE.
