Cisco MDS 9000 Series IPStorage (IPS) services extend the reach of Fibre Channel SANs by using open-standard, IP-based technology. The switch connects separated SAN islands using Fibre Channel over IP (FCIP) and it allows IP hosts to access Fibre Channel storage.
 Note |
The FCIP feature is available in the modules with IPS ports and available in Cisco MDS 9250i, MDS 9220i, and Cisco MDS 9700 Director switches. |
The Cisco MDS 24/10 Port SAN Extension Module for MDS 9700 series switch allows you to use Fibre Channel and FCIP features. The Cisco MDS 24/10 port SAN Extension Module can be used in any of the Cisco MDS 9700 series switches.
This chapter includes the following sections:
This section briefly describes the new and updated features for releases, starting from Cisco MDS NX-OS Release 9.x.
| Feature | Release | Description |
|---|---|---|
| Configuring 40 Gbps Speed on Cisco MDS 24/10 port SAN Extension Module | 9.3(1) | This feature allows you to configure 40-Gbps speed on the IPS ports of Cisco MDS 24/10 port SAN Extension Module. |
You can configure the FCIP and iSCSI features on the following types of hardware:
Cisco MDS 24/10 port SAN Extension Module in Cisco MDS 9700 Series Director Switches and Cisco MDS 9220i Fabric Switches support FCIP.
Cisco MDS 9250i Multiservice Fabric Switches support iSCSI.
ISSU/D is disruptive for FCIP and iSCSI interfaces along with the update of the underlying IPS and GigabitEthernet interfaces supporting these upper layer interfaces. Fibre Channel interfaces (including FC interfaces on the same module or switch as the IPS and GigabitEthernet interfaces), FCoE Ethernet interfaces, and supervisor modules are all updated nondisruptively.
Within Cisco MDS 9700 Directors, the modules with IPS ports implement a 5 minute delay before the next module with IPS ports is upgraded.
Starting from Cisco MDS NX-OS Release 8.5(1), the Cisco MDS 9220i Fabric Switch is supported. Cisco MDS 9220i switch supports six IPS ports. Ports 1 through 4 support 1- and 10-Gbps speed and port 6 supports 40-Gbps speed. By default, the first two ports are operating at a 1-Gbps speed mode and are licensed. To enable the other ports and different speed modes, you must obtain a license. You cannot move the default license from the first two ports to any other ports. For information on port licensing, see the Cisco MDS 9000 Series Licensing Guide.
Cisco MDS 9220i switch supports three 1 or 10 Gbps IPS ports, one 1, 10, 25 Gbps IPS port, one 25 Gbps IPS port and one 40 Gbps IPS port. All these ports are handled by a single Service Engine. The below table provides the different speed combinations that can be configured on the IPS ports of Cisco MDS 9220i switch.
The IPStorage interfaces operating in 25G-speed-mode require FEC RS-IEEE. The Ethernet interface of the connected switch must also be configured to use FEC RS-IEEE. If an IPStorage interface remains stuck in the init state, configure the Ethernet interface on the connected switch to use FEC RS-IEEE.
| Speed mode | Port 1 | Port 2 | Port 3 | Port 4 | Port 5 | Port 6 |
|---|---|---|---|---|---|---|
| 1 Gbps | 1 Gbps | 1 Gbps | 1 Gbps | 1 Gbps | Out-of-service | Out-of-service |
| 10 Gbps | 10 Gbps | 10 Gbps | 10 Gbps | 10 Gbps | Out-of-service | Out-of-service |
| 25 Gbps | Out-of-service | Out-of-service | Out-of-service | 25 Gbps | 25 Gbps | Out-of-service |
| 40 Gbps | Out-of-service | Out-of-service | Out-of-service | Out-of-service | Out-of-service | 40 Gbps |
Note |
25-Gbps speed is supported from Cisco MDS NX-OS Release 9.3(1). |
From Cisco MDS NX-OS Release 8.5(1), you can configure 40 Gbps on the IPS ports 9 and 10 of Cisco MDS 24/10 port SAN Extension Module. Cisco MDS 24/10 port SAN Extension Module supports eight 1 or 10 Gbps IPS ports and two 40 Gbps IPS ports. Ports 1 through 4 and port 9 and handled by Service Engine 1 and Ports 5 through 8 and port 10 and handled by Service Engine 2. Each Service Engine has the capability of 40 Gbps. You can only configure 40 Gbps speed on ports 9 and 10. When you configure 40 Gbps speed on port 9, ports 1 through 4 are moved to out-of-service because the Service Engine capability is 40 Gbps. However, ports 5 through 8 can be configured for 1 or 10 Gbps speed provided port 10 is not configured for 40 Gbps speed. Similarly, when you configure 40 Gbps speed on port 10, ports 5 through 8 are moved to out-of-service. However, ports 1through 4 can be configured for 1 or 10 Gbps speed provided port 9 is not configured for 40 Gbps speed. The following table provides the different speed combinations that can be configured on the IPS ports of Cisco MDS 24/10 port SAN Extension Module.
The following are the recommended configurations for achieving maximum throughput on the 40 Gbps IPS port:
The maximum bandwidth of FCIP tunnel is 10 Gbps. Therefore, configure four FCIP tunnels on the 40 Gbps IPS port. To create the FCIP tunnels, create four VLAN sub interfaces on the 40 Gbps IPS port. On each VLAN create an FCIP tunnel.
Configure the number of TCP connections to 5.
| Service Engine 1 | Service Engine 2 | ||
|---|---|---|---|
| Ports 1 through 4 | Port 9 | Ports 5 through 8 | Port 10 |
| 1 Gbps | Out-of-service | 1 Gbps | Out-of-service |
| 10 Gbps | Out-of-service | 10 Gbps | Out-of-service |
| 1 Gbps | Out-of-service | 10 Gbps | Out-of-service |
| 10 Gbps | Out-of-service | 1 Gbps | Out-of-service |
| Out-of-service | 40 Gbps | 1 Gbps | Out-of-service |
| Out-of-service | 40 Gbps | 10 Gbps | Out-of-service |
| 1 Gbps | Out-of-service | Out-of-service | 40 Gbps |
| 10 Gbps | Out-of-service | Out-of-service | 40 Gbps |
| Out-of-service | 40 Gbps | Out-of-service | 40 Gbps |
Both FCIP and iSCSI rely on TCP/IP for network connectivity. On each Fibre Channel module with IPS ports, connectivity is provided in the form of IP storage ports on Cisco MDS 9250i switches and Cisco MDS 9700 series switches with 24/10 port SAN Extension modules that are appropriately configured. This section covers the steps required to configure IP for subsequent use by FCIP and iSCSI.
A new port mode, called IPS, is defined for IP storage ports on each Fibre Channel module with IPS ports. IP storage ports are implicitly set to IPS mode, so it can only be used to perform iSCSI and FCIP storage functions. IP storage ports do not bridge Ethernet frames or route other IP packets.
Each IPS port represents a single virtual Fibre Channel host in the Fibre Channel SAN. All the iSCSI hosts connected to this IPS port are merged and multiplexed through the single Fibre Channel host.
In large scale iSCSI deployments where the Fibre Channel storage subsystems require explicit LUN access control for every host device, use of proxy-initiator mode simplifies the configuration.
 Tip |
IPStorage ports on any Fibre Channel module with IPS ports should not be configured in the same IPS broadcast domain as the management IPS port—they should be configured in a different broadcast domain, either by using separate standalone hubs or switches or by using separate VLANs. |
The following figure shows an example of a basic IPStorage IP version 4 (IPv4) configuration.
Note |
The port on the Ethernet switch to which the IPStorage interface is connected should be configured as a host port (also known as access port) instead of a switch port. Spanning tree configuration for that port (on the Ethernet switch) should disabled. This helps avoid the delay in the management port coming up due to delay from Ethernet spanning tree processing that the Ethernet switch would run if enabled. For Cisco Ethernet switches, use either the switchport host command in Cisco IOS or the set port host command in Catalyst OS. |
IPS core dumps are different from the system’s kernel core dumps for other modules. When the Fibre Channel module with IPS port’s operating system (OS) unexpectedly resets, it is useful to obtain a copy of the memory image (called a IPS core dump) to identify the cause of the reset. Under that condition, the Fibre Channel module with IPS ports sends the core dump to the supervisor module for storage. Cisco MDS switches have two levels of IPS core dumps:
Partial core dumps (default)—Each partial core dump consists of four parts (four files). All four files are saved in the active supervisor module.
In Cisco MDS 9700 Series Switches with 24/10 port SAN Extension Modules, each partial core dump consists of five parts (five files). All five files are saved in the active supervisor module.
Use the show cores command to list these files.
Full core dumps—Each full core dump of Cisco MDS 9250i Switches and SSN-16 modules consists of 64 parts (64 files), and each full core dump of Cisco MDS 9700 Series Switches with 24/10 port SAN Extension Modules consists of 67 parts (67 files). The IPS core dump for MSM-18/4 modules consists of 32 parts. This dump cannot be saved on the supervisor module because of its large space requirement. They are copied directly to an external TFTP server.
Use the system cores tftp: command to configure an external TFTP server to copy the IPS core dump (and other core dumps).
To configure IPS core dumps on the Fibre Channel module with IPS ports, follow these steps:
| Command or Action | Purpose | |
|---|---|---|
|
Step 1 |
switch# config terminal |
Enters configuration mode. |
|
Step 2 |
switch(config)# ips core dump full |
Configures a dump of the full core generation for all Fibre Channel module with IPS ports in the switch. |
|
Step 3 |
switch(config)# no ips core dump full |
Configures a dump of the partial core (default) generation for the Fibre Channel module with IPS ports in slot 9. |
Configuring Autonegotiation
By default, autonegotiation is enabled on all the IPStorage interface. You can enable or disable autonegotiation for a specified IPStorage interface. When autonegotiation is enabled, the port automatically detects the speed or pause method, and duplex of incoming signals based on the link partner. You can also detect link up conditions using the autonegotiation feature.
Configuring the MTU Frame Size
You can configure the interfaces on a switch to transfer large (or jumbo) frames on a port. The default IP maximum transmission unit (MTU) frame size is 1500 bytes for all Ethernet ports. By configuring jumbo frames on a port, the MTU size can be increased up to 9000 bytes.
Note |
The minimum MTU size is 576 bytes. |
Tip |
MTU changes are disruptive, all FCIP links and iSCSI sessions flap when the software detects a change in the MTU size. |
Configuring Promiscuous Mode
You can enable or disable promiscuous mode on a specific IPStorage interface. By enabling the promiscuous mode, the IPStorage interface receives all the packets and the software then filters and discards the packets that are not destined for that IPStorage interface.
Virtual LANs (VLANs) create multiple virtual Layer 2 networks over a physical LAN network. VLANs provide traffic isolation, security, and broadcast control.
IPStorage ports automatically recognize Ethernet frames with IEEE 802.1Q VLAN encapsulation. If you need to have traffic from multiple VLANs terminated on one IPStorage port, configure subinterfaces—one for each VLAN.
If the Fibre Channel module with IPS ports or MPS-14/2 module is connected to a Cisco Ethernet switch, and you need to have traffic from multiple VLANs coming to one IPS port, verify the following requirements on the Ethernet switch:
The encapsulation is set to 802.1Q and not ISL, which is the default.
Use the VLAN ID as a subscription to the IPStorage interface name to create the subinterface name:
<slot-number> / <port-number>
<VLAN-ID>IPStorage interfaces (major), subinterfaces (VLAN ID), and management interfaces (mgmt 0) can be configured in the same or different subnet depending on the configuration (see the following table).
| Interface 1 | Interface 2 | Same Subnet Allowed | Notes |
|---|---|---|---|
| IPStorage 1/1 | IPStorage 1/2 | Yes | Two major interfaces can be configured in the same or different subnets. |
| IPStorage 1/1.100 | IPStorage 1/2.100 | Yes 1 | Two subinterfaces with the same VLAN ID can be configured in the same or different subnets. |
| IPStorage 1/1.100 | IPStorage 1/2.200 | No | Two subinterfaces with different VLAN IDs cannot be configured in the same subnet. |
| IPStorage 1/1 | IPStorage 1/1.100 | No | A subinterface cannot be configured on the same subnet as the major interface. |
| mgmt0 | IPStorage 1/1.100 | No | The mgmt0 interface cannot be configured in the same subnet as the IPStorage interfaces or subinterfaces. |
| mgmt0 | IPStorage 1/1 | No |
Note |
The configuration requirements in the above table applies to Ethernet PortChannels also. |
After the IPStorage interfaces are connected with valid IP addresses, verify the interface connectivity on each switch. Ping the IP host using the IP address of the host to verify that the static IP route is configured correctly.
Note |
If the connection fails, verify the following, and ping the IP host again:
|
Tip |
If IPv4-ACLs are already configured in a IPStorage interface, you cannot add this interface to an Ethernet PortChannel group. |
Follow these guidelines when configuring IPv4-ACLs for IPStorage interfaces:
Only use Transmission Control Protocol (TCP) or Internet Control Message Protocol (ICMP).
Note |
Other protocols such as User Datagram Protocol (UDP) and HTTP are not supported in IPStorage interfaces. Applying an ACL that contains rules for these protocols to a IPStorage interface is allowed but those rules have no effect. |
Apply IPv4-ACLs to the interface before you enable an interface. This ensures that the filters are in place before traffic starts flowing.
Be aware of the following conditions:
If you use the log-deny option, a maximum of 50 messages are logged per second.
The established , precedence , and fragments options are ignored when you apply IPv4-ACLs (containing these options) to IPStorage interfaces.
If an IPv4-ACL rule applies to a preexisting TCP connection, that rule is ignored. For example if there is an existing TCP connection between A and B, and an IPv4-ACL specifies dropping all packets whose source is A and destination is B is subsequently applied, it will have no effect.
Virtual Router Redundancy Protocol (VRRP) and Ethernet PortChannels are two IPStorage features that provide high availability for iSCSI and FCIP services.
VRRP provides a redundant alternate path to the IPStorage port for iSCSI and FCIP services. VRRP provides IP address failover protection to an alternate IPStorage interface so the IP address is always available (see the below figure).
In the above figure, all members of the VRRP group must be IPStorage ports. VRRP group members can be one or more of the following interfaces:
One or more interfaces in the same Fibre Channel module with IPS ports or MSM-18/4 module
Interfaces across Fibre Channel module with IPS ports or MSM-18/4 modules in one switch
Interfaces across Fibre Channel module with IPS ports or MSM-18/4 modules in different switches
IPStorage subinterfaces
Ethernet PortChannels and PortChannel subinterfaces
You can configure no more than seven VRRP groups, both IPv4 and IPv6, on a IPStorage interface, including the main interface and all subinterfaces.
To configure VRRP for IPStorage interfaces using IPv4 or IPv6, follow these steps:
|
Step 1 |
switch1# config terminal Enters configuration mode. |
||
|
Step 2 |
switch(config)# interface IPStorage 2/2 Enters the interface configuration mode on the IPStorage interface (slot 2, port 2). |
||
|
Step 3 |
To configure VRRP for IPStorage interfaces using IPv4: |
||
|
Step 4 |
To configure VRRP for IPStorage interfaces using IPv6:

The Cisco Discovery Protocol (CDP) is supported on the management Ethernet interface on the supervisor module and the IPStorage interfaces on the Fibre Channel module with IPS ports or MSM-18/4 module.
For information about configuring CDP, refer to the Cisco MDS 9000 Series NX-OS Fundamentals Configuration Guide.
This sections includes the following topics:
The Cisco MDS 9250i Multiservice Fabric Switch has two IPStorage interfaces that support 1 Gbps and 10 Gbps link speeds. By default, IPStorage interfaces are configured at 10 Gbps link speed.
Switching between different link speeds is supported on Cisco 10 Gbps IPStorage platforms starting from Cisco MDS NX-OS Release 6.2(13). An ISSD to a release earlier than Cisco MDS NX-OS Release 6.2(13) when any of the IPStorage ports are configured at 1 Gbps, is disallowed. Reconfigure such ports back to the default link speed of 10 Gbps before attempting such a downgrade.

%IF_DOWN_SOFTWARE_FAILURE: %$VSAN 1%$ Interface fcip is down (Port software failure)If there is a mismatch between the configured link speed and the small form-factor pluggable (SFP) speed capabilities, the port goes into an Error Disabled state and a corresponding syslog message is logged. In such a scenario, either the configured link speed or the SFP should be changed. If the link speed is changed, even if the port is already enabled, the shutdown and no shutdown commands must be explicitly issued for the change to be applied.
