Hi experts,
I need to cope configuration from one switch/firewall to another switch/firewall.
I have copied running configs.
The question is do I have to clear the existing configuration on the dest. devices
Or can I copy it(replace) directly without clearing previous config ?

Happy ThanksGiving guys,
I'm working on a script that will use nmap to enumerate a network for active cisco switches. Once the list is complete, we use sed to clean up the file (called nmapres) so it is only a list of IP addresses. Next I want to use a while statement to go down that list of... (6 Replies)
NG_CISCO(4) BSD Kernel Interfaces Manual NG_CISCO(4)NAME
ng_cisco -- Cisco HDLC protocol netgraph node type
SYNOPSIS
#include <sys/types.h>
#include <netinet/in.h>
#include <netgraph/ng_cisco.h>
DESCRIPTION
The cisco node type performs encapsulation and de-encapsulation of packets using the Cisco HDLC protocol. This is a fairly simple protocol
for the transmission of packets across high speed synchronous lines. Each packet is prepended with an Ethertype, indicating the protocol.
There is also a ``keep alive'' and an ``inquire'' capability.
The downstream hook should connect to the synchronous line. On the other side of the node are the inet, inet6, atalk, and ipx hooks, which
transmit and receive raw IP, IPv6, AppleTalk, and IPX packets, respectively. Typically these hooks would connect to the corresponding hooks
on an ng_iface(4) type node.
IP Configuration
In order to function properly for IP traffic, the node must be informed of the local IP address and netmask setting. This is because the
protocol includes an ``inquire'' packet which we must be prepared to answer. There are two ways to accomplish this, manually and automati-
cally.
Whenever such an inquire packet is received, the node sends a NGM_CISCO_GET_IPADDR control message to the peer node connected to the inet
hook (if any). If the peer responds, then that response is used. This is the automatic method.
If the peer does not respond, the node falls back on its cached value for the IP address and netmask. This cached value can be set at any
time with a NGM_CISCO_SET_IPADDR message, and this is the manual method.
If the inet hook is connected to the inet hook of an ng_iface(4) node, as is usually the case, then configuration is automatic as the
ng_iface(4) understands the NGM_CISCO_GET_IPADDR message.
HOOKS
This node type supports the following hooks:
downstream The connection to the synchronous line.
inet IP hook.
inet6 IPv6 hook.
atalk AppleTalk hook.
ipx IPX hook
CONTROL MESSAGES
This node type supports the generic control messages, plus the following:
NGM_CISCO_SET_IPADDR
This command takes an array of two struct in_addr arguments. The first is the IP address of the corresponding interface and the second
is the netmask.
NGM_CISCO_GET_IPADDR
This command returns the IP configuration in the same format used by NGM_CISCO_SET_IPADDR. This command is also sent by this node type
to the inet peer whenever an IP address inquiry packet is received.
NGM_CISCO_GET_STATUS
Returns a struct ngciscostat:
struct ngciscostat {
u_int32_t seq_retries; /* # unack'd retries */
u_int32_t keepalive_period; /* in seconds */
};
SHUTDOWN
This node shuts down upon receipt of a NGM_SHUTDOWN control message, or when all hooks have been disconnected.

HISTORY
The ng_cisco node type was implemented in FreeBSD 4.0.

BUGS
Not all of the functionality has been implemented. For example, the node does not support querying the remote end for its IP address and
netmask.
