Why disable cdp for back-to-back serial connection? [7:62764]
Dear all, From cisco configuration example http://www.cisco.com/en/US/tech/tk713/tk317/technologies_configuration_examp le09186a00800944ff.shtml I'm wondering that the line no cdp enable is required for both router in order to make a serial connection up for back-to-back connection.

Re: Why disable cdp for back-to-back serial connection [7:62798]
Dear Priscilla, Thank you for your clear explaination. May be it is better to disable cdp for low speed link, and security issue. Regards, Lawrence Priscilla Oppenheimer wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Cisco Discovery Protocol (CDP) is a managment protocol that allows routers and switches to tell each other about their IOS version, hardware platform, and basic config info. Some security experts say to disable it because it tells too much. It has nothing to do with bringing the serial interface up/up. You could use it or you could not. The two routers on the HDLC link don't have to agree. One could send CDP while the other doesn't and the link should still come up/up, assuming everything is OK at the physical and data-link layers. It's too bad they used no cdp enable in that simple example with no explanation. I don't think it's the default? So someone had to type it in, so they should have explained it.

SNMP - Backplane OID for Catalyst 3524XL [7:14955]
Has you tried to monitor Catalyst 3524XL backplane utilization? I tried Cisco_stack_mib such as .1.3.6.1.4.1.9.5.1.1.8 and .1.3.6.1.4.1.9.5.1.1.32 but no response. Any suggestion.

FEC between two Catalyst. [7:8373]
Here is my case: 2 Catalyst 2924XL : CAT_1 configuration (simplified) ! interface FastEthernet 0/22 ! interface FastEthernet 0/23 port group 1 ! interface FastEthernet 0/24 port group 1 ! interface VLAN1 ip address 10.5.30.253 255.255.255.0 ip default-gateway 10.5.30.254 ! CAT_2 Configuration (simplified) ! interface FastEthernet 0/22 ! interface FastEthernet 0/23 port group 1 ! interface FastEthernet 0/24 port group 1 ! interface VLAN1 ip address 10.5.30.252 255.255.255.0 ip default-gateway 10.5.30.254 ! Hope the above info is enough. Problem: I am able to telnet both Catalysts from a PC from a 10.5.31.0/24 network, but I can't telnet/ping from CAT_1 command line interface to CAT_2 VLAN1 ip or e versa. Is the problem caused by FEC between them? Any suggestion.
