vims range

To limit the Local VE IDs a hypervisor HBA driver can use, use the vims range command. By restricting the Local VE ID range to use a subset of bits in the CS_CTL field, it can be partitioned and shared with future Fibre Channel features.

vmis range rangevsan id

Syntax Description

range

Specifies the low range and high range values for Virtual Machine Identifier (VMID). The range is from 1 to 255.

vsan id

Specifies a VSAN ID for which the range is being configured.

Command Default

None

Command Modes


Configuration mode (config)

Command History

Release

Modification

8.2(1)

This command was introduced.

Usage Guidelines

There is no mechanism in the VMID protocol for the Virtual Machine Identification Server (VMIS) to notify the attached hypervisor HBA driver clients of a new VE ID range. For clients to detect a new range, they must query the VMIS again. To force the clients to query again after a range modification, the user must manually log the FCIDs out and back in to the fabric. Therefore, local clients continue to tag the VM traffic with the previous range until this occurs. This restriction applies when enabling and disabling VMID, and changing the VE ID range of a VSAN.

Examples

This example shows how to configure multiple Local VE ID ranges for use by VEMs in a VSAN:


switch# configure terminal
switch(config)# vmis range 3-45,51-70 vsan 1

Related Commands

Command

Description

Command History

Release

Modified

1.0(2)

This command was introduced.

3.0(1)

  • Added the IPv6 option.
  • Added the address and advertisement-interval options that are specific to IPv6.

Usage Guidelines

You enter the Virtual Router configuration submode to access the options for this command. From the VSAN or mgmt0 (management) interface configuration submode, enter vrrp number to enter the switch(config-if-vrrp)# prompt. By default, a virtual router is always disabled (shutdown ). VRRP can be configured only if this state is disabled. Be sure to configure at least one IP address before attempting to enable a virtual router.

The total number of of VRRP groups that can be configured on a Gigabit Ethernet port, including main interfaces and subinterfaces, cannot exceed seven. This limitation applies to both IPv4 and IPv6 groups.


Note
If you configure secondary VRRP IPv6 addresses on an IPFC VSAN interface, you must remove the secondary VRRP IPv6 addresses before downgrading to a release prior to Cisco Release 3.0(1). This is required only when you configure IPv6 addresses.

Examples

The following example enables VRRP configuration: 


switch(config-if-vrrp)# no
 shutdown

The following example disables VRRP configuration: 


switch(config-if-vrrp)# shutdown

The following example configures an IPv4 address for the selected VRRP: 


switch# config terminal
switch(config)# interface vsan 
1  switch(config-if)# vrrp 250
 
switch(config-if-vrrp)# address 10.0.0.10

This command was introduced.

3.0(1)

Usage Guidelines

Examples

The following example assigns an iSCSI initiator to a VSAN other than the default VSAN: 


switch# config terminal 
Enter configuration commands, one per line.  End with CNTL/Z.
switch(config)# iscsi initiator name iqn.1987-02.com.cisco.initiator
switch(config-iscsi-init)# vsan 40
switch(config-iscsi-init)#

The following example assigns an iSLB initiator to a VSAN other than the default VSAN:

DANGER

vsan suspend command done on an active VSAN is a very invasive command that requires a lot of supervisor processing. The supervisor is responsible for logging each device out, deprogramming ACLs, removing FCNS entries, generating RSCNs, etc. Because of this, care should be taken when doing this when there are many devices logged into the switch in the VSAN. After suspending the VSAN a minimum of 5 minutes should elapse prior to doing an no vsan suspend to ensure that all of the prior processing has completed.

Examples

The following example shows how to suspend a VSAN and enable interop mode 4: 


switch# config t
switch(config)# vsan database
switch(config-vsan-db)# vsan 100 suspend

switch(config-vsan-db)#

vsan wwn fcid

To allocate an FCID to a WWN in the persistent FCID database, use the vsan wwn fcid command. To remove this allocation, use the no form of this command.

vsan vID wwn wID fcid fID [ area ] [ dynamic ]

no vsan vID wwn wID fcid fID [ area ] [ dynamic ]

Syntax Description

vsan vID

Specifies the VSAN ID. Range is 1–4093.

wwn wID

Specifies the MAC address. The address is in the format hh:hh:hh:hh:hh:hh:hh:hh.

fcid fID

Specifies the persistent FCID. Range is 0x0-0xffffff.

area

(Optional) Specifies to reserve all non xxxx00 FCIDs in the specified domain and area from being allocated to devices.

dynamic

(Optional) Marks the entry as a dynamic type.

Command Default

A unique FCID is allocated to a WWN the first time it FLOGIs in to the switch.

Command Modes


FCID database configuration submode (config-fcid-db)

Command History

Release

Modification

1.1(1)

This command was introduced.

Usage Guidelines

To assist in predictability, the MDS switch has the capability to always assign the same FCID to the same WWN of a device that logs in to the fabric. This allows devices to be zoned by FCID, for example. When the persistent FCID database is enabled, a vsan vID wwn wID fcid fID configuration line is automatically added whenever a device FLOGIs in to the switch. There may be occasions where this configuration needs to be manually manipulated, for example when an HBA is replaced then the old WWN must be removed from the FCID and the new HBA WWN assigned to the same FCID.

To allow only a single FCID to be allocated in a particular domain and area, set the last 2 digits of the fcid argument as 00 and use the area option. This causes the xxxx00 FCID from the domain and area to be allocated to the WWN and the 255 remaining FCIDs in the area to be unavailable.

The dynamic keyword marks an entry as purgeable by the purge fcdomain fcid command. If an entry is static (not marked as dynamic) then it will be ignored by the purge fcdomain fcid command. Entries automatically created by the system in the FCID persistent database are marked as dynamic.

To avoid assigning a duplicate FCID, use the show fcdomain address-allocation vsan command to display the FCIDs that are in use.

Examples

The following example displays how to configure the WWN of a device with an FCID in VSAN 10 as a static entry:


switch# configure
Enter configuration commands, one per line.  End with CNTL/Z.
switch(config)# fcdomain fcid database
switch(config-fcid-db)# vsan 10 wwn 33:e8:00:05:30:00:16:df fcid 0x070128

The following example displays how to configure the WWN of a device with an FCID in VSAN 10 as a dynamic type entry:
