• Using the no form of a command 53
• Example the following shows an example of the extensions made to the cli show commands for the output filtering feature 54
• Filter displayed output to only include lines containing a specified string match filter displayed output to exclude lines containing a specified string match filter displayed output to only include lines including and following a specified string match filter displayed output to only include a specified section of the content e g interface 0 1 with a configurable end of section delimiter string matching should be case insensitive pagination when enabled also applies to filtered output 54
• For new commands for the feature see cli output filtering commands on page 194 54
• Grep like control for modifying the displayed output to only show the user desired content 54
• Note although some switch show commands already support pagination the implementation is unique per command and not generic to all commands 54
• Output filtering 54
• Supports enabling disabling paginated output for all show cli commands when disabled output is displayed in its entirety when enabled output is displayed page by page such that content does not scroll off the terminal screen until the user presses a key to continue more or q uit is displayed at the end of each page 54
• When pagination is enabled press the return key to advance a single line press q or q to stop pagination or press any other key to advance a whole page these keys are not configurable 54

• Use the remark keyword to add a comment remark to an ip standard or ip extended acl the remarks make the acl easier to understand and scan each remark is limited to 100 characters a remark can consist of characters in the range a z a z 0 9 and special characters space hyphen underscore remarks are displayed only in show running configuration one remark per rule can be added for ip standard or ip extended acl user can remove only remarks that are not associated with a rule remarks associated with a rule are removed when the rule is removed 630

• This command creates a new rule for the current ip access list a rule may either deny or permit traffic according to the specified classification fields at a minimum either the every keyword or the protocol source address and destination address values must be specified the source and destination ip address fields may be specified using the keyword 635
• To indicate a match on any value in that field the remaining command parameters are all optional but the most frequently used parameters appear in the same relative order as shown in the command format 635
• Use this command to renumber the sequence numbers of the entries for specified ip access list with the given increment value starting from a particular sequence number the command is used to edit the sequence numbers of acl rules in the acl and change the order in which entries are applied this command is not saved in startup configuration and is not displayed in running configuration 635

• Format 646
• If a time range with the specified name does not exist and the ipv6 acl containing this acl rule is applied to an interface or bound to a vlan then the acl rule is applied immediately if a time range with specified name exists and the ipv6 acl containing this acl rule is applied to an interface or bound to a vlan then the acl rule is applied when the time range with specified name becomes active the acl rule is removed when the time range with specified name becomes inactive for information about configuring time ranges see time range commands for time based acls on page 671 646
