IP Management Subcommands:
atm add ARP [<netif>] <host> <ATM address>
where: <netif> is the optional name of the network interface the ATMARP entry is to be associated with. If no name is specified, a network interface is chosen depending on the IP address of the host being added. <host> is the host name or IP address of the host to be added to the ATMARP table, <ATM address> is the ATM address of the host.
This command adds an entry to the ATMARP table for ATM. The given hosts IP address is associated with the given ATM address. When IP needs to transmit data to the host, the specified ATM address will be used to open an SVC.
The entry will be marked as permanent in the ATMARP table and will not be subject to aging.
atm add PVC <interface> <vpi> <vci> <aal> <encaps> IP <netif> [<host> | dynamic] <traffic> <params...>
where: <interface> specifies the physical interface where the PVC is to terminate, <vpi> specifies the Virtual Path Identifier (VPI) of the PVC, <vci> specifies the Virtual Channel Identifier (VCI) of the PVC, <aal> specifies the ATM Adaptation Layer (AAL) for the PVC. Valid choices are "null" or "AAL0" for the null AAL; "AAL1" for AAL 1; "AAL2" for AAL 2; "AAL3", "AAL4", or "AAL3/4" for AAL 3/4; and "AAL5" for AAL 5, <encaps> specifies the encapsulation for the PVC. Valid choices are "null" or "none" for null encapsulation, and "LLC/SNAP", "LLC", or "SNAP" for LLC/SNAP encapsulation, IP specifies that the owner of the PVC is IP. <netif> specifies the network interface which the PVC is to be associated with. The network interface must exist and be associated with the specified physical interface, <host> | dynamic gives the address of the host at the far end of the PVC, or the word "dynamic" if its address is to be determined with Inverse ARP. If "dynamic" is specified, LLC/SNAP encapsulation must also be specified. <traffic> is the traffic type of the PVC and may be one of UBR, CBR or VBR. Following the traffic type the traffic parameters must be given. For UBR and CBR this is the peak cell rate and for VBR these are the peak and sustainable cell rate and the maximum burst size.
This command creates a PVC with the specified attributes and attaches it to IP.
atm delete ARP [<netif>] <host>
where: <netif> is the optional name of the network interface the ATMARP entry is associated with. If no name is specified, the specified host is deleted from the cache regardless of what network interface it is associated with. <host> is the host name or IP address of the host to be deleted from the ATMARP table.
This command deletes the specified hosts entry from the ATMARP table.
atm set arpserver <netif> <ATM address> | local [<IP prefix> ...]
where: <netif> specifies the network interface for which the ATMARP server address is to be set. <ATM address> specifies the ATM address of the host which is to provide ATMARP service. If "local" is specified instead of an ATM address, the host on which the command is issued will become the ATMARP server. <IP prefix> ... is an optional list of IP prefixes that the ATMARP server will provide information about. An IP prefix is specified as a dotted decimal IP address, followed by a slash, followed a number specifying how many bits of the IP address are significant. For example, 10.0.0.0/8 indicates that the ATMARP server will provide services for all addresses on IP network 10. The IP subnetwork which the network interface belongs to is automatically included.
This command sets the address of the ATMARP server for a network interface.
atm show ARP [<host>]
displays the following information:
Net Intf - the network interface which traffic for the entry will use.
Flags - flags showing whether the entry is valid and whether it is permanent. - flags giving further information about the ATMARP entry. The meanings of the characters in the flags are:
P - the entry is permanent
R - the entry has been refreshed
V - the entry is valid
Age - the number of minutes for which the entry will remain valid.
Origin - the source of the ATMARP entry. Possible values are: LOCAL ---- The entry is for an interface on the host. PERM ----- The entry is permanent. This is used for entries that are created with the add ARP command. REG ------ The entry was created as the result of a host registering with the ATMARP server. SCSP ----- The entry was learned via SCSP. LOOKUP --- The entry was created as the result of a host performing an ATMARP lookup. PEER_RSP - The entry was created as the result of a host answering an InARP Request. PEER_REQ - The entry was created as the result of a host sending an InARP Request.
ATM address - the ATM address of the host the entry refers to.
IP address - the IP address or domain name of the host the entry refers to.
If no parameters are specified on the show ARP subcommand, the whole ATMARP table will be displayed. If a host name or IP address is specified, only information about the given host is displayed.
This command displays both information that has been learned dynamically (through one form or another of ATMARP and via SCSP) and information which has been configured by the user (through the add ARP subcommand).
atm show arpserver [<netif>]
displays the following information:
Net Intf - the network interface for which information is being displayed.
State - the state of the connection to the ATMARP server. Possible values are: NOT_CONF - No ATMARP server has been configured for the interface. SERVER --- The host is the ATMARP server. PEND_ADR - No ATM address has been set for the interface. POPEN ---- The host is attempting to open a VCC to the ATMARP server. REGISTER - The host has a VCC open to the ATMARP server and is in the process of registering with the server. ACTIVE --- The ATMARP server connection is active.
ATM Address - the ATM address of the ATMARP server.
If no parameters are specified on the show arpserver subcommand, the ATMARP servers for all network interfaces will be displayed. If an interface name is specified, only information about the given network interface is displayed.
atm show IPVCC [<host> | <netif>]
displays the following information:
Net Intf - the name of the network interface at which the VCC terminates.
VPI - the Virtual Path Identifier (VPI) for the VCC.
VCI - the Virtual Channel Identifier (VCI) for the VCC.
State - the state of the VCC. Possible values are: PMAP ---- The host has an IP packet to send and is waiting for an ATMARP mapping. POPEN --- The VCC is being opened. PACCEPT - A VCC from a remote host is being accepted. ACTPENT - A PVC is open, but no ATMARP information is available for it yet. ACTIVE -- The VCC is active.
Flags - flags giving further information about the VCC. The meanings of the characters in the flags are:
S - the VCC is an SVC
P - the VCC is a PVC
L - the VCC uses LLC/SNAP encapsulation
M - the IP-to-ATM address mapping for the VCC is valid
N - there is no idle timeout for the VCC
IP Address - the name and IP address of the host at the remote end of the VCC.
If no parameters are specified on the show IPVCC subcommand, all active VCCs are displayed. If a host name is specified, the active VCC(s) for the given host are displayed. If a network interface name is specified, the active VCC(s) for the given network interface are displayed.
