In the NE Explorer, select an NE and choose Communication > Access Control from the Function Tree.
In the Ethernet Access Control area, if the Ethernet Access is disabled, it is impossible to login the NE by the T2000 and Navigator which is connected to this
There are two ways to enable the Ethernet Access:
1. If there are other NEs connected to that disabled Ethernet Access NE by Optical Supervisory Channel or Electrical Supervisory Channel. The we can login any one
of other NEs first, then login that disabled Ethernet Access NE. Then, In the NE Explorer, select an NE and choose Communication > Access Control from the
Function Tree. In the Ethernet Access Control area, click Refresh to query the Ethernet access enable status.Check the Enable Ethernet Access check box and
click Apply. The Ethernet access function for the NE is enabled.
If that disabled Ethernet Access NE is an isolated NE, or only with extended ECC connecting to other NEs. There is not any other NEs connected that NE with
Optical Supervisory Channel or Electrical Supervisory Channel. Then we must connect to that disabled Ethernet Access NE by internal LAN ports(ETH1/ETH2/ETH3) through Telnet, and then login to the SCC boards. (#17SCC IP is 192.168.0.250，#18 SCC IP is 192.168.0.251). Then do the following steps:
run this command:
new symbol "liulin" added to symbol table.
liulin = 0x3fc6590: value = 1 = 0x1
run this command:
Run this command:
value = 102472536 = 0x61b9b58
Run the command:
value = 0 = 0x0
Login the NE in navigator from NM_ETH1/NM_ETH2, run this command to set Ethernet Access Enabled.
After the Ethernet Access is disabled, the access authority of NM_ETH1 and NM_ETH2 are both cancelled. So, it must be impossible to login NE by these two
LAN ports. Furthermore, at this time, their extended ECC is also disabled.
