Hi Sajjad, This CLI requires the ‘del' to be placed in at the right place: set interface ip address del GigabitEthernet2/4/0 1.2.2.0/24<http://secure-web.cisco.com/126mo_uLAOrpU_akFQK3wD98sektPzbzvnGHGi9yo7UuhwA3eQEIICAZc5mVcXSaFNLKEFL0Cn40pb3UkTKoBjAJUUIi00pK-V6BmM9f6ANF7da_iH4f6HhNzn5VvNSbAEasMUN4AhPXMGwcOrsWV2ecXM1tEB9joxR0QAYs1_iYNAp_yFCAA2NSqrc9fzSruSrg95uA9nu1KkvgPw3RNJIBdPkkEcPz2fB3-YSNfSBNTkAPjzvoyIOWt6QpUcNwVO5Ry7uZDCdVaLUJrwvy-b-M-FBAjwmiPlEBLMopqMCPY9c_izS1ybC5avOGH2dZw/http%3A%2F%2F1.2.2.0%2F24>
With the ‘del’ at the end it is not interpreted and so the command is considered to be an add – hence the conflict. If you would like to submit a patch to fix this it would be appreciated.
