I put access list in my cisco 2950 to restrict telnet. I have permitted my ip address 176.17.8.10 but i can no longer telnet that device. Here is the info. and access list.

Info:
cisco 2950 : 176.17.254.32

Vlan 8
My PC: 176.17.8.10

access-list 101 permit tcp host 176.17.8.10 host 176.17.254.32 eq telnet

line vty 0 15
access-class 101 in

What is the problem why I cannot get in to that switch.

Please anybody could help.

Thanks in advance...

When I run Synthesize about the code below, the Synthesize runs a long time and does not stop. May someone can tell me the reason? thanks!
PS: I use ise.

library ieee;
use ieee.std_logic_1164.all;
use ieee.std_logic_unsigned.all;

entity vgaram is
port( clk : in std_logic;
addr : in std_logic_vector(12 downto 0);
data_o : out std_logic_vector(0 to 7);
data_i : in std_logic;
rwenable : in std_logic
);
end vgaram;

architecture vgaram_arch of vgaram is

type ramtype is array(0 to 19) of std_logic_vector(0 to 7);
signal vedioram : ramtype :=
(
"00000000","00000000","00000000","00000000","00000 000","00000000","00000000","00000000","00000000"," 00000000",
"00000000","00000000","00000000","00000000","00000 000","00000000","00000000","00000000","00000000"," 00000000"

);


begin

process(clk)
begin
if clk'event and clk = '1' then
if rwenable = '0' then
vedioram(conv_integer(addr(12 downto 3)))(conv_integer(addr(2 downto 0))) <= data_i;
else
data_o <= vedioram(conv_integer(addr(12 downto 3)));
end if;
end if;
end process;
end vgaram_arch;

hi. It means correct. Did you check other access device between 2960 and your PC?

My PC is directly connected to the Cisco 2950 switch.

Are there any other entries in the access list? I mean before the one the permit one? If yes then keep the permit entry as the first one in sequence and see. Order of entries is important in access lists

Thanks

Also one more catch, keep the destination address as "any" or loopback interface on the router.
