Blok ip ganjil atu genap ACL
Blok IP ganji ataupun genap dari network 192.168.0.0 255.255.255.0
If it is 0, the IP address will be Even
-If it is 1, the IP address will be Odd
192.168.1.00000001 = 192.168.1.1 – odd
192.168.1.00000011 = 192.168.1.3 – odd
192.168.1.00000010 = 192.168.1.2 even
192.168.1.00000100 = 192.168.1.4 even
FOR Even Networks
The IP address will be 192.168.1.0
With the wild card mask as 0.0.0.254
254 = 11111110
Here, 0 means DO CARE of the last bit in IP address (must be ZERO)
For Odd Networks
The IP address will be 192.168.1.1
With the wild card mask as 0.0.0.254
254 = 11111110
Here, 0 means DO CARE of the last bit in IP address (must be ONE)

Reset Password Cisco router
Cara reset password Cisco router seri 2500 ke atas:
1. Matikan tombol router terus nyalakan lagi dan tekan ctrl+shift + break.
2. Akan masuk ke ROMMON...( Rommon> )
3. Ketik confreg 0x02142 trs tekan enter
4. Masih di Romon ketik reset trs enter
5. Router akan reboot dan seperti biasa pilih no:
6. Anda sudah masuk ke router dan bisa ubah password
7. jangan lupa copy run-start
8. Masuk ke global config dan ketik 'configuration-register 0x2102
Untuk yang model sebelum seri 2500 ke bawah beda lagi:
1. Sama spti diatas masuk ke Rommon
2. Ketik 'o/r enter
3. Ketik 'i' (tanpa tanda '') enter
4.selebihnya sama dengan diatas.
