1) try to connect laptop on direclty connected switch under vlan 1 but unsuccessful
2 ) make port as trunk between switch and HP blade switch and pass all vlan but ping was not ok
3) connect one laptop on huawei switch and put it into vlan 4 and then ping to server was successful.
4) on further checking we found that port connect to HP blade has vid 1 but on HP blade side vid was 4 and the ports were tagged as vlan 4 and ports were untagged as vlan 1 .
5) so we change vid as 4 on huawei switch , so it start working or alternately change tagged as vlan 1 on HP server .,, both solutions work
